Product description

This product is insoluble in water, soluble in toluene, etc. It has the excellent characteristics of small compression deformation and resistance to saturated vapor pressure. In aviation, electronics, machinery, chemical industry and other industrial sectors, it can be used to manufacture high and low temperature resistant sealing materials and waterproof and moisture-proof insulating materials. And because of its physiological inertness, it can be used to produce artificial organs and medical tubes, and raw materials for high-temperature kneading silicone rubber.

Performance and Application

Raw materials for high temperature mixing of silicone rubber, wear-resistant oil for shoe soles, and pressure-sensitive adhesives.

Chemical definition

It is copolymerized by dimethylsiloxane and a small amount of vinylsiloxane, and a small amount of unsaturated vinyl is introduced to improve its vulcanization process and product performance. It has small compression deformation, saturated steam resistance, hydrophobicity, physiological inertness, Moisture-proof, electrical insulation, high and low temperature resistance and other excellent characteristics.

Application industry

1. Silicone rubber: the basic raw material for producing and mixing silicone rubber;

2. Shoe material: It can be used as an additive for TPR, PU and other elastomers to increase the wear resistance of the sole;

3. Chemical industry: Additives for the production of modified plastics, such as adding a small amount to automotive panels, can increase its finish.

【Packaging, storage and transportation】

1. The product is packed in clean and dry cardboard boxes lined with plastic bags, with a net content of 25kg per box;

2. Transportation: When the product is transported, it should be protected from rain and sunlight, and it should be transported as non-dangerous goods. Light loading and unloading during handling to prevent packaging damage;

3. Storage: The product should be stored in a ventilated and dry warehouse to prevent direct sunlight. This product has a storage period of 3 years from the date of production. If it exceeds the storage period, it can be re-sampled and tested according to the standard. If it meets the standard requirements, it can still be used.
