Silicone precision rubber roller

Silicone is increasingly favored by people for its environmental performance. To understand the knowledge of silicone products, you must start with silicone raw materials.

1. Silicone raw materials can be divided into ordinary silica gel and meteorological silica gel according to their performance.

Ordinary silica gel

Color: translucent, milky white, light yellow, gray, etc.

Hardness: 30°, 40°, 50°, 60°, 70°, etc., commonly used between 40° and 70°.

Density: 1.1-1.12g/cm2

Elongation: 400%

Uses: The most used are low-end silicone products such as mobile phone buttons, miscellaneous pieces, conductive adhesives.

Meteorological glue, also known as pure silica gel

Color: transparent.

Hardness: 30°, 40°, 50°, 60°, 70°, 80°, etc., commonly used between 40° and 60°.

Features: Due to the transparency of this material, the tensile strength is strong. High cost

Uses: Silicone tube, protective cover and other high-end products that require high elasticity.

2. The raw materials of silica gel can be divided into solid silica gel and liquid silica gel according to physical properties.

Solid silica gel is mainly used for compression molded products. For example: silicone sleeve, silicone tableware, silicone buttons, etc., liquid silicone is mainly used for extrusion molding products, such as silicone nipples, silicone tubes and so on.

Insulation silicone pad, excellent high temperature resistance, silica gel (food grade silica gel) can withstand high temperature of 200 ° C and can be used for a long time. The raw materials of this product meet the SGS standard, and pass the FDA food grade silica gel detection standard, tasteless and non-toxic, manufacturers rely on The mold produces the sealing ring, and the color and shape of the silicone sealing ring can be customized.

The rubber sealing strip is a sealing strip made of rubber. Rubber sealing strips are mainly used in automobiles, machinery, doors and windows, etc., and play the role of dustproof, insect proof, waterproof, fixed, soundproof, shock absorption and sealing. Generally, it is made of rubber materials such as neoprene rubber, EPDM rubber, silicone rubber, fluororubber, rubber and rubber, and other rubber materials with excellent aging resistance. The manufacturing method includes extrusion molding continuous vulcanization method and extrusion molding vulcanization tank vulcanization. Method and molding vulcanization method, etc.

Due to its high temperature resistance, oil resistance, high vacuum resistance, acid and alkali resistance, and resistance to various chemicals, fluororubber has been applied to cutting-edge technologies such as modern aviation, missiles, rockets, space navigation, ships, and atomic energy, as well as automobiles, shipbuilding, and chemistry. , petroleum, telecommunications, instruments, machinery and other industrial fields.

EPDM rubber has good elasticity and compression deformation resistance, aging resistance, ozone, chemical action, and wide temperature range. Automotive sealing strips are mainly made of EPDM foamed and densely compounded. Unique metal clamps and tongue-shaped buckles for durability and ease of installation.
