Analysis of Platinum Cured Silicone Rubber

Difference between platinum cured silicone rubber and silicone

There are many different forms and synthetic way of silicone rubber. Platinum is a catalyst which is a promotion of chemical reactions of substances. High-performance platinum catalyst with high efficiency, can inhibit the Si- Vi and Si- H reaction accompanied by side effects in the process and avoid the generation of the black substance. Generally, the product is appearing yellow or black phenomenon when the other catalysts are used in the product. So, you can prepare high transparent products by adding the platinum catalyst, and the transparency can be more than Japan, the United States, Germany and other similar foreign products. In a word, Platinum cured silicone rubber with high purity and quality as well as its unique properties is more superior to the ordinary silicone rubber products.

Description of platinum cured silicone rubber

Platinum cured silicone rubber is also called two-part addition silicone rubber that vulcanizes at room temperature. Part A is a flowable liquid, part B is the curing agent (platinum catalyst). The two components of Part A and part B are mixed by the ratio of 1:1. Platinum cured silicone rubber with translucent appearance is a kind of FDA grade silicone. It’s most suitable for molds making application.

Applications of platinum cured silicone rubber

Platinum cured silicone rubber has come into our life. It basically has the following four aspects. Firstly, Platinum cured silicone rubber can be used for epoxy resins, polyester resins, polystyrene, vinyl plastic, wax and other materials mold. Secondly, it is widely used in concrete stone, plaster casting, culture stone, large cement components and other products mold manufacturing. Then, platinum cured silicone rubber can applicable to candy, biscuits, cakes, chocolate and any other food product molds making. In addition, we also can use it to create our kitchen supplies mold.

Characteristics of platinum cured silicone rubber

Ⅰ Almost nil shrinkage (less than 0.1% )

Ⅱ Good tear strength (this feature ensures higher resistance to wearing and shearing)

Ⅲ High dimensional stability over time and non-deformability

Ⅳ High temperature resistant in 250 Centigrade

Ⅴ Exceptional fluidity and good operability (mixing ratio at 1:1 )

Ⅵ High chemical resistance to aggressive components of some types of resins

Ⅶ Food grade silicone (environmental, odorless and nontoxic)
