Product Description


Silicon rubber series products are high-tech products that developed by Xi’an Sunward Aeromat Co.,Ltd aiming at market demand. They are high-tear-resisting rubber products converted to civilian use which have high strength on aero scale.

The materials our company uses for silicon rubber vulcanization are methyl vinyl silicon rubber type110-2 which are provided by well-known raw rubber suppliers in China. We use fumed high-reinforce white carbon black impacted from CABOT as the ingredient for rubber strength reinforce. Using advanced technique to vulcanize and heat the rubber material two or more times in order to reinforce the physical properties of the products. The products can be used for long-term at from -60℃ to 250℃ and maintain high strength at high temperature, even at 300℃ can them be put for short-term use and still maintain the physical properties.

The silicone rubber sheet, rubber rope and all kinds of seal and dielectric products made by our company using high-tech formula and advanced technology have been successfully applied to many industries such as aviation, automobile, electronic, electrical equipments and aerospace industry. In addition, these products have already been widely used among lots of domestic dry-type transformer manufacturers. The silicone rubber products produced by our company have reached military standard HG6-677/698-74.

Our Company

In 1992, as military products as it used to be, Sky Rubber became the first program that converted to civilian use in Academy of Aerospace Solid Propulsion Technology(AASPT). It opened an era of military rubber converted to civilian use on transformer rubber seal products. In 1996, Sky Rubber drew up <Standard of seal products for transformers JB8448.1-2004> together with National Standard Committee. Gathering all the military technology resources, Sky Rubber filled up the technology gap in this industry by develop high-voltage-specific SF6 EPDM rubber products, high-voltage-electric-specific fluoro rubber, dry-type-transformer-specific silicon rubber and heat resisting and weather aging resisting acrylate rubber products.
In the development of market, Sky Rubber inherits the astronautic spirit of safety, reliability and infallibility and constantly persists in the highest standard of quality and complete quality assurance system and always prioritizes customer experience. Sky Rubber will always make sure that every single piece of products is excellent and fine by series of technology improvement and the application to advanced manufacture management.
