?XinhuaXu silicone seal improved !!!

??XinhuaXu rubber products company specializing in the production of high-quality rubber seals, high-quality rubber seals contribute to a better functioning machine. Especially silicone seals, we improved the formula of raw materials, product quality and yield are greatly improved.

??Now many XinhuaXu rubber seals produced have a hint of fragrance, like the original did not want to have an acrid smell of rubber. XinhuaXu especially silicone seals, silicone polymer molecule by Si-O (Si - O) bond together into a chain structure, which constitute the first high molar mass linear polysiloxane. Since the Si-O-Si bond is a bond which constitutes the basic type silicon atom primary convergence group, the introduction of a very small amount of unsaturated groups on the side chains, small intermolecular forces, molecular spiral structure, methyl outwardly placing and rotating freely, so compared to other general rubber silicone rubber having excellent heat resistance, electrical insulation and chemical stability. A typical silicone rubber that is polydimethyl siloxane formaldehyde, to have a helical molecular structure, a smaller force between its molecules and therefore have outstanding resilience, together with formaldehyde-based point outside the spiral can be freely rotated, thus making silicone rubber function have a common appearance, such as the appearance of anti-blocking property and water repellency.

??XinhuaXu rubber seals widespread use of high-quality rubber seals have a clean surface gloss, rounded shape, torn edges neat no glitches, no scratches. Hand feels smooth. Silicone seals did not seem too technical content, but in reality the production of high-quality silicone seals need a number of factors.

Silicone is generally 10 to 80 Shore A hardness can give you choose the desired hardness, viscosity and hardness is usually proportional to viscosity. High-intensity resistance can be cut after it was placed under high torsional stress, heat and sulfur-type solid silicone rubber can not be torn. Need rubber seals silicone material can be Xu Xinhua order!
