Q:How long is the warranty period for EPDM?

(1). Rubber molding, after pressing, the elastic body is within the cohesion can not be eliminated, the molding die, often have a very unstable contraction (rubber shrinkage due to rubber vary), required after a period of time, and can be stable. Therefore, when a rubber product design at the beginning, regardless of formula or mold, it is necessary to carefully calculate the coordination, if not, it is easy to produce product size instability, resulting in lower quality products.(2). A rubber elastic body of thermosetting plastic hot melt, belongs to the hot cold setting. Rubber due to different types of sulfide species, its molding and curing temperature range is also a considerable gap, and even can be affected by climate change, indoor temperature and humidity affected. Therefore, the production conditions of rubber products need to be adjusted at any time. If not, the quality of the products may be different.(3) rubber products are made of rubber raw materials and used as raw materials made from the rubber compound of the mixer, and the formula is designed according to the characteristics of the required rubber products, and the required hardness of the products is determined. The product is made and molded by rubber flat vulcanizing machine. Finally, the product is processed by flying edge, and the surface of the product is treated smoothly without burrs.(4). Aging test of rubber products aging test belongs to the category of rubber aging refers to rubber and products in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors caused by the performance of the structure change, then the loss of use value phenomenon. They are crazing, sticking, hardening, softening, powdering, discoloration, mildew, etc..

Q:How can rubber products prevent fading?

Light and white rubber products are prone to yellowing in the course of use and storage, thus affecting appearance and quality, resulting in various economic disputes and irreversible losses.

Q:Is vulcanized sole good or rubber sole is good?

Vulcanized soles are vulcanized rubber, after vulcanization, this step of rubber products are not easy to aging, cracking, good elasticity, heat resistance, and now the rubber products are basically this kind of rubber, also known as mature rubber, collectively referred to as rubber or rubber

Q:What is the rubber composition of sole?

The sole of high pressure polyethylene and rubber flavor, rubber and plastic used together.Student: Rubber soled heavy, expensive, not resistant to oil, heat. Variable color.

Q:PVC conveyor belts and rubber belts differ from each other in their respective advantages

PVC is actually a vinyl polymerization substance, whose material is a non crystalline material. PVC materials often use stabilizers, lubricants, auxiliary processing agents, pigments, anti shock agents and other additives in practical use. Is not flammable, high strength, excellent resistance to climate variability and geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is also not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

Q:How can rubber be preserved without decay?

The sealing environment of rubber seals should be boring, which is also an important factor to avoid aging. In summary, the reserve environment for rubber seals is light, cool and boring.

Q:How are rubber wires processed?

[summary] the main raw material is rubber, rubber products with various agents, as well as the fiber and metal skeleton material, the basic production process of rubber products including plastication, mixing, calendering, extrusion, molding, curing 6 basic processes.The processing process of rubber is mainly to solve the process of plastic and elastic contradictions, through various means of processing, the elastic rubber has become the plastic rubber, adding various in the preparation of semi-finished products, and then through the vulcanization is has semi-finished plastic and rubber products into high elasticity and good mechanical performance the.

Q:What is the tensile strength of silicone rubber?

The main characteristics of silicone rubber:High and low temperature performance, the range is -100-300 degrees centigrade.Ozone aging, heat resistance, oxygen aging and weather aging are good.The electric insulation performance is good, can do high-grade insulation products.It has excellent biomedical properties, non-toxic and tasteless.Good sealing performance.

Q:How can the rubber shoes be dyed?

The sole of balata bottom shoe according to the specific distinction of material, can be divided into natural balata bottom shoe, wear-resisting balata bottom shoe, balata bottom shoe, mix balata bottom shoe, EVA balata bottom shoe. The sole uses the chemical synthesis material to be many, generally selects the cold resistant material in winter, in summer must choose the anti - high temperature material.

Q:Does the fuel pipe for automobiles belong to rubber products?

If it is a diesel car, then the high pressure part of the metal pipe only, in the low pressure part of the rubber tube.
