China’s Commody Prices Exploring in Environmental Inspections

2017-08-12

China is adjusting the industrial structure, leading to a environmental friendly, rather than over consume the resource and at the cost of damaging the Environment.

The seven round of Environmental Inspections launched in Auguest, and this trend will be last till March 2018. The phenomenon of raw materials shortage and soaring will be absolutely deteriorating, as more and more factories will be forced and shut down to recitfy and productivity will be restricted.

China launched the Seven round Environmental Inspections

2017-7-27

As China’s Environmental Inspections keep proceeding deeper and deeper, the seven round has been launched. This round could be estimated more harsher than previous rounds. All raw materials soars in immediate response.

Below is quoted from the official announce from Ministry of Environmental Protection The People’s Republic of China.

Technical Explanation of Liquid silicone rubber's Working time

When we talk about silicone rubber's working time, there is one important factor that always been mentioned: the working condition (working temperature.). People who used liquid silicone rubber before all know temperature has great impact on the silicone rubber's setting time, no matter for Tin-cured or Platinum-cured. Indeed, Platinum-cured silicone is even more sensitive to temperature.

Some users sometimes get confused that when silicone rubber come to their place from the suppliers’, they always have much different working time with the suppliers’, Even they exactly follow technical instruction.Surely, there are other factors that affect the working time and curing time, humidity for example, also has more or less impact, but here we focus on the temperature only.

To discuss how temperature affect the working time, we should presume the humidity is the same, and also, the supplier makes the correct instruction based on their lab test. Therefore, there two temperatures will be discussed, one is working temperature, one is liquid silicone’s temperature.

1. Working temperature. When Inno Silica test the working time, we normally set it under room temperature at around 25 degree. When silicone reach to client’s place and if their working temperature is different from 25 degree, the working time will be different. The higher temperature, the shorter working time. vice versa.

2. But under same working temperature, why the working time is still different from the instruction? There is one more important factor that always been neglected, which is liquid silicone’ temperature. The liquid silicone store under certain condition, it will get a certain temperature. For example, when the silicone is stored under room temperature 10℃, when it takes out and work under 25 ℃, with air conditioner, the liquid silicone rubber and catalyst’s temperature is actually much less than 25℃. When mix two parts together, the working time obtained will still much longer. Vice versa, when silicone rubber store under 30℃, for example, when it takes out to work under 25℃， the working time will be shorter than what supplier instructed.

By knowing these two factors, now we know how to avoid the impact from the temperature and how to get a suitable working time by yourself. Here are some advises and tips for Tin-Cured silicone rubber:

1.You could follow the intruction by the supplier first. If the working time and curing time are far more than you required, please try the second or third step.

2. After takes out the silicone from warehouse, judge the temperature of both silicone rubber and working temperature. If these temperatures are higher than what supplier instructed, please lower the mixing ration of catalyst a little bit. If your storage temperature and working temperature are lower than supplier’s instruction, better to increase the mixing ratio a little bit.

3. Before want to use the silicone rubber, you also could take out the silicone rubber from warehouse to leave it under the working temperature for around 10~24 hours till it closes to the working temperature. But this will take times.

4. If you still have problems after the three steps, please contact your supplier for further technical support.

Polysiloxane decides what its ultimated product Forms

Polysiloxane ( (R2SiO)x ),

is a polymer with repeated Si-O as main chain, and each Si atom direct connect with organic group. In its chemical formulas, R represents organic group which could be methyl, phenyl etc.

In Polysiloxane, the ratio of R/Si decides what its ultimated product form is:

When R/Si ＜2, the ultimated product is Silicone Resin;

When R/Si ≈2, the ultimated product is Silicone rubber;

When R/Si ＞2 the ultimated low molecular weight, oil like product, namely silicone oil.

How Addition cure silicone rubber is made?

For many years, most of the Silicone Rubber manufacturers only focus on promoting their products, rather than explain how silicone rubber is made and what are its components.

Surely, there is patent and special ingredients concern, but the general processes and raw materials of the silicone rubber should be known by clients.

Here, Inno Silica (www.innosilicone.com, contact: [email protected] ) takes this opportunity to discuss how the addition cure silicone, namely RTV-2 food grade silicone is made.

Part One Vinyl Silicone Fluid

First, let’s start with Vinyl Silicone fluid. Vinyl Silicone Fluid is a kind of polysiloxane, which contains 2 or more than 2 -Si-CH=CH2. It is the main ingredients of silicone rubber. Through adding Vinyl Silicone Fluid, it could change silicone rubber’s crosslink density, and therefore enhance the tear and tensile strength as welll as hardness.

Part Two. Major Conponents of Addition Cure Silicone rubber

1. Silicone Base

Silicone base is mostly Polydimethylsiloxane which contains with 2 or more than 2 -Si-Ch=CH2. Normally, it is a type of linear Polysiloxane that brings each Vinyl at each end. (If brings only one Vinyl in one end, it calls Vinyl silicone oil )

2. Crosslinker

Crosslinker is a kind of Organic silicon oligomer which contains 3 or more than 3 -Si-H, also called methyl hydrogen silicone oil. It is one of basic components of Addition cure silicone rubber.

3. Catalyzer

There are mainly catalyzers that could initiate the Si-H reaction in Addition cure silicone rubber, but only Platinum catalyzer is the most efficient. By applying the Platinum catalyst, the addition cure silicone rubber could be vulcanized in room temperature. And by adding proper ratio of inhitor into the catalyzer, it could prolong the reaction speed and control the vulcanization.

4. Rainforce Fillers

Silicone rubber made by Vinyl Silicone Fluid and Hydrosilicone Fluid only does not have good mechanical properties, which means its tear and tensile strength, elongation etc are not good. In order to improve its mechanical properties, rainforce fillers should be added. These fillers normally are fume silica, precipitation silica, silicone powder...If want to get the clear silicone rubber, Methyl vinyl MQ silicone resin will be added to improve clear silicone’s mechanical properties.

5. Other additives

Other additives are added with the purposes of getting different colors, thermal conductiivity, flame resistance, electrical conductivity,thermostability, transparency, ect.

To get more information about silicone knowleage, technology and other supportive information, please pay attention to our website or follow our facebook, Tumblr...we will update some information, including the product information, new products, latest development...

ADDITION CURE SILICONE also called Platinum-cured silicone rubbers that consist of two parts (Part A & Part B). After mixing, they cure at room temperature to flexible, high-strength rubbers. Addition cure silicones are more prefer to condensation cure silicone s, due to their food grade, none shrinkage and more resistant to higher temperature, aging, worse environment conditions.

Features • Exhibit Non-shrinkage after curing, optimal for casting highly precise and dimensional stable parts • No release agent required �� High tear strength and tensile strength, long library life • Excellent resistance to high temperature, chemicals and aging • Food grade, skin touch safety

Typical Uses & Casting Materials • Same uses with condensation cure silicones Typical Uses in: • Food product molding, including Candy/Chocolate/Cake molding • Life casting • Polyurethane, epoxy, polyester resins casting • Dimensional stable parts Rapid Prototyping

CAUTION During mold making, mixture should be avoided to contact with some material which may inhibit the curing system. These materials include: 1. Organotin and other metallorganic compound 2. sulphur, polysulfide, polysulfone and other sulfur-containing 3. Amine, polyester rubber and other ammoniac 4. phosphorig and other phosphorig-containing
