Product Description
HTV quality or high-temperature vulcanized silicone rubber is used in the compression molding press. Special silicone rubber materials are chosen based on their intended use, whether they need to be fire, oil, or heat resistant. Food and medical qualities have FDA and BFR approvals.
HTV silicone has been widely used to replace petrochemical products in all industries including aerospace, munitions industry, automobile, fine chemicals, construction, electric and electronics, food processing, mechanical engineering, medical and pharmaceutical, cosmetics, home appliances, paper film, solar batteries, and semiconductor. Recently, the scope of silicone applications has been expanding at a greater speed.

Silicone Rubber HTV Properties
1. Temperature resistance: silicone rubber can withstand extreme temperatures and remain stable under extreme stress conditions and harsh environments without affecting use. It can work under -90?? 350? for a long time.
2. Durable: silicone rubber has excellent insulation, heat resistance, oil resistance, aging resistance, which means that it has a long service life.
3. Other properties: silicone rubber also has excellent performances in weather resistance, water repellent, electrical insulation, physiological inertness after vulcanization
Silicone Rubber HTV Application
According to its vulcanization temperature, silicone rubber can be divided into two categories: high-temperature vulcanization type and room temperature vulcanization type, silicone rubber HTV is mainly used in the manufacture of various silicone rubber products. Today, the application of silicone rubber HTV is becoming wider and wider in aerospace and aviation industries for the manufacturing of the components used in the interior and exterior of aircraft or spacecraft. silicone rubber can be also found in mold making, auto industry, electronic industry and other industries such as machinery, construction, textile, chemical, light industry, and printing.
Process of Silicone Rubber HTV
Silicone Rubber HTV is high molecular weight molecular weight is generally 400,000 800,000 of polyorganosiloxane i.e. raw rubber with reinforcing fillers and various other additives, using organic peroxide as vulcanizing agent, by pressure molding molding, extrusion, calendering or injection molding, and at high temperature cross-chain into rubber.
Description of Clear Silicone Rubber Liquid
Clear silicone rubber liquid is relative to solid high-temperature vulcanized silicone rubber, which is a liquid rubber with good fluidity, fast vulcanization, more safe and environmentally friendly, and can fully meet the requirements of food grade. Clear silicone rubber liquid can be used for coating, impregnation and infusion. For example, the viscosity of 0.0750 Pa-sec/25? of hydroxyl capped polydimethylsiloxane, with methyl vinyl bis-pyrrolidone silane as chain growth agent, with organic peroxides, such as dibenzoyl peroxide, 25-dimethyl ground 5-di-tert-butyl peroxyhexane as vulcanizing agent, such rubber has good fluidity and low viscosity, and in its Vulcanization process at the same time chain growth reaction, so you can get high molecular weight elastomer, with good physical and mechanical properties. Chain growth agent methyl vinyl dipyrrolidone silane, can be obtained from the reaction between pyrrolidone and methyl vinyl dichlorosilane in the presence of triethylamine, the product is easy to hydrolyze, so it needs to be stored in a dry and closed container, the pyrrolidone group of this compound can react slowly with the end hydroxyl group in polydimethylsiloxane at room temperature, and its reaction speed is accelerated with the increase of temperature.
Overview of Liquid Silicone Rubber Products
Typical liquid silicone rubber products are soft and elastic non-toxic and odorless transparent, medical safety that is food safety is extremely high, and can be used for artificial breast filler. Liquid silicone rubber products added to the functional materials such as electrical conductivity, thermal conductivity and waveguide can be given the corresponding function. Other applications such as mold making, electronic module potting.
