Silicone rubber products reach new heights, WACKER showcases new technology products.snack cup silicone sales

　　In recent years, the global chemical industry has continued to expand its technical scope. Since the beginning of 10 years, a variety of chemical products have been explored, developed and realized. In recent years, Wacker Chemical Group, the upstream of organosilicon chemical industry, has also continued to make progress. WACKER CHEMICALS GROUP participated in the German Rubber Conference and displayed a variety of addition-crosslinking solid silicone rubbers in the silicone rubber processing industry. Among them, the main product named ELASTOSIL R plus 4001 is as follows.

　　This type of silicone rubber products are widely used, and for the first time, they have shown new hardness performance, which can highlight the advantages compared with the hardness of conventional silicone products on the market. First public meeting at the German Rubber Conference. Another high-temperature solid silicone rubber called ELASTOSIL R plus 4350/55 was another highlight of WACKER's presentation at the conference. With the assistance of thermal stabilizers, the product can withstand temperatures up to 300 degrees Celsius without significant changes in elastic or mechanical properties.

　　According to the introduction, for the solid silicone rubber compound, ELASTOSIL R plus 4001 is more convenient to process, has better elasticity after launch and two outstanding properties and is more efficient, compared with comparable peroxide cross-linked rubber, The time required for cross-linking can be reduced by up to 50%, which can help manufacturers shorten processing time and greatly increase production capacity. The resulting vulcanizate also has good mechanical properties, flexibility, and strong plasticity, which can maintain its original properties for many years. The molded parts that have undergone constant temperature curing treatment are suitable for the production of various industrial silicone accessories and required seals, including food-grade environmental protection.

　　other aspects

　　Its shore hardness is 20 degrees, which is relatively soft in the silicone product industry, but it has excellent elasticity, and the elongation at break is as high as 1200%, which means that the vulcanizate of this product can be stretched to its original length. 12 times without cracking and without losing mechanical properties. The second product is the opposite, with hardness on the opposite end of the scale: ELASTOSIL R plus 4001/90 has a hardness of 90 degrees, which is almost identical to thermosets. Although the elongation at break of this solid silicone rubber is 140%, it is still elastic, bendable and stretchable by comparison. Since the vulcanizate is suitable for sensitive applications it is perfectly suitable for use in the food sector.

　　In addition, ELASTOSIL R plus 4350/55 is a silicone rubber that can be used to formulate high temperature resistant addition-crosslinking silicone elastomers. When WACKER developed this product, special consideration was given to how it works optimally with the thermal stabilizer in the base rubber, so that the type and amount of stabilizer can be decisive for the thermal stability of the vulcanizate. The product can be processed without difficulty using the extrusion silicone process.

　　Seals and silicone hoses made with ELASTOSIL R plus 4350/55 can withstand temperatures of up to 300 degrees Celsius, even for several days, without any damage. A number of high-temperature tests have shown that even if the product is exposed to a high temperature environment above 200°C for 2000 hours, the important mechanical properties of the product such as Shore hardness and elongation at break are hardly affected. After cross-linking, it has a hardness of up to Shore A 55 and is especially suitable for the production of high temperature silicone seals such as oven doors or silicone elements in engine compartments. Post-cured vulcanizates meet the requirements of the German Federal Institute for Risk Assessment (BfR) and the US Food and Drug Administration (FDA) for direct food contact products.
