The CPU product is produced by casting. Because the raw material is liquid, it is suitable for making large or very large elastomer products and very complicated product types.
As a polymeric elastomer material, polyurethane is a new type of material between rubber and plastic. It has high mechanical strength, good elasticity in a wide range of hardness, excellent wear resistance, oil resistance, low temperature resistance, ozone resistance and radiation, so it is widely used.
The main product types of CPU elastomer: 1. PU rods and plates
The PU rod has a standard mold, the length is 300MM, and 500MM, produced by a casting machine, the product is solid and hollow. These products are mainly used as springs and stamping dies to cushion. The elastic parts are mainly used in mechanical equipment such as punching machines, which can protect the equipment from damage and ensure the quality of the products. PU rods are used in many industries and can be machined to make the required parts and parts.
PU board: It can produce products of different thickness, length and width. PU board is mainly used for cushioning, compression and load bearing, such as molding equipment, sand blasting machine room, steel factory, ceramics factory, electronics, grain, building, etc. A workplace that requires the elasticity and wear resistance of a PU sheet. The PU board can be processed into seals, molds and accessories as needed.
The special-purpose wear-resistant group anti-static liner can be used in the silo pipe of the port terminal, the belt unloader and the construction machinery.
PU slabs are available in polyether, polyester and specialty polyols, with different materials and different properties and environments. The polyether type has good elasticity and low temperature flexibility, and has excellent hydrolytic stability. Polyester type products are resistant to oil, corrosion, weak acid and alkali, and wear resistant than polyether. Therefore, according to the use environment and performance requirements of the product, the raw materials to be used should be selected.
Second, PU sheet, coil
The thickness of PU sheet is from 0.5MM to 16MM, the width is 300MM, 500MM, 600MM, 1000MM, etc. It is generally polyether type, widely used in electronics, ceramics, grain, machinery manufacturing, machining and other industries; Static sheets can be used in electronics and electrical production lines.
PU squeegee: According to the environment used, squeegee is divided into two categories, one is mainly used in ceramic glazing line, wood industry and other industries with very low polar solvent content; the other is solvent-resistant squeegee This type of product is mostly used in circuit board manufacturers and printing industries. The squeegee is a polyester type product, and the hardness and size of the product vary depending on the model and product requirements used.
Color: natural, red, green, blue, brown, etc.
Hardness: 50A, 55A, 60A, 65A, 70A, 75A, 80A, 85A thickness; 5MM, 7MM, 8MM, 9MM, 10MM Width: 35MM, 40MM, 45MM, 50MM
Third, the use of CPU products in all walks of life, such products are generally non-standard parts, according to customer requirements, and need mold to be processed.
