Xinhua Xu silicone rubber seals

Xinhua Xu silicone rubber seals are commonly used in some of the fluid in the pipe more, mostly in order to prevent the intrusion of the media and the sealing parts, sealing materials generally rubber seals should meet the needs of the majority of sealing requirements, and in combination with different characteristics, the main requirement for the sealing material is really very simple, most of them will now have to use rubber, the main functional requirements need to have rubber seals, material good compactness easy to leak, and have the appropriate mechanical strength hardness at high temperatures is not easy to soften decompose for compressibility and resilience, and good resistance to aging, durable, has sealing surface paste the full flexibility, ease of manufacture and processing, cheap, easily drawn.

Silicone ring polymer molecules 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 comfortable place and rotated so that the silicon rubber other than ordinary rubber seals have very good heat resistance, electrical insulation and chemical stability. A typical silicone rubber seal 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 seals have a common appearance functions, such as water repellency and release of the look.

Each feature Xinhua Xu silicone rubber seals have its usefulness:

1, the conditioning hardness silicone rubber seal has a Shore A hardness scale 10-80, which give plenty of freedom to the designer to select the desired hardness in order to best accomplish a particular function. Other heat curing time and temperature, and it will not damage other physical characteristics.

2, hardness is proportional to viscosity and viscosity under normal circumstances can be conditioned. That has a Shore A hardness scale 10-80, then it has much viscosity scale.

3, this exceptional tensile strength in tensile strength so that it can be made into a variety of silicone rubbers, such as heated solid organic sulfur-type silicone rubber, fluorosilicone rubber, liquid silicone rubber.

4, 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.
