FAQ

Does the fuel pipe for automobiles belong to rubber products?
First of all, make sure that your car is gasoline or diesel, and what parts to follow.
How to test the abrasion resistance of rubber?
Rubber: the word "rubber" comes from the Indian language "cau-uchu", meaning "weeping tree"". Natural rubber is flowing out from the Hevea latex when tapping after solidification and drying process. The finished product is material with elasticity, insulation, waterproof and air.
How long is the warranty period for EPDM?
The warranty period for rubber products (EPDM) is about 1--6 months.
How can there be a crack in the rubber ring?
Problems in production:1) formulation design, oil or resin less material or caused by excessive or high temperature, poor liquidity and other reasons!2) when manufacturing, the product appears the hole which the exhaust is not good3) the raw material is too thick during production, and cracks are also caused.
How long does the rubber last?
In addition, aging has ozone aging, weather aging, heat aging and so on. Ding Qing rubber is not resistant to ozone, the time is not long, it will appear aging.
What does the rubber tire do to people?
Rubber is an elastic polymer. Rubber can be obtained from the plant sap, can also be man-made, both have many applications and products, such as tires, washers, etc., has become an important economic crop. The cultivation of rubber is mainly concentrated in Southeast Asia, such as Thailand, Malaysia and Indonesia.
Is carbon black and conductive carbon black used in rubber?
Rubber carbon black and conductive carbon black are mainly distinguished from the function of the product, so the performance requirements of carbon black are different.The carbon black used in rubber mainly focuses on the physical properties of carbon black, and its abrasion resistance and tensile properties are performed according to the requirements of the national standard GB3778-2003. Market commonly used models can be divided into N219, N220, N330, N326, N550, N660, N774, etc., the specific application of the industry is different, but the choice of different models.Conductive carbon black value is the conductivity of carbon black, than the resistance, oil absorption value indicates the conductive carbon black conductive properties, according to the national standard GB3782-2006 GB requirements. According to the purpose of distinction is usually divided into three categories of battery grade rubber grade conductive carbon black, conductive carbon black, conductive carbon black ink level, the specific requirements of the various industries are not the same, there is no specific normative guidance documents, actual test and application specific to choose different manufacturers.
Is rubber flame retardant?
Mainly to see the use of related products, for example, the glass door rubber strip is flame retardant, and the vehicle's internal and external tires are not flame retardant.
