According to the difference of Raw material, It have different function products. Normally it have
Two types Polyurethane and Polyether. It can apply in producing plastic, rubber,fibre,Hard and soft foamed plastics,adhesion agent and coating material and so on. Polyurethane materials can be used in various fields of national life, and the range of application is very wide. Here are some of the representative products are briefly introduced.
olyurethane. Polyurethane elastomer has very good tensile strength, tear strength, impact resistance, abrasion resistance, weather resistance, hydrolysis resistance, oil resistance and other advantages. Mainly used as coating materials (such as gaskets, hoses, belt, roller, gear, piping etc.), insulator, sole and solid the tire and so on.
PU V belt
Classification of transmission belt:
The transmission has two functions: transmission and speed change,It is divided into two categories: friction drive and meshing drive. So far,The V belts, flat belts, toothed belts and circular belts have been formed in the structure of the belt mills in the world, and the four systems have been formed,More than 1000 kinds of sizes have been appears.Especially toothed belts,In recent ten years,With the progress of precision machinery and electronic information technology.Polyurethane miscellaneous order, as a high-tech product of rubber industry in the world, development is very rapid, production has expanded dramatically. The transmission belt variety classification.
Toothed belt, also called synchronous belt,It can be divided into two types: one side toothed belt and two sided toothed belt.The former is mainly used in single shaft transmission,The latter is multi axis or reverse transmission,A new type of high efficiency belt in the world since 1980.The toothed belt is divided into two kinds: trapezoid and arc according to the shape of tooth.The torque of the synchronous belt with circular teeth is large.From the materials used,olyurethane parts, belt type rubber and polyurethane can be divided into two types.The former is divided into ordinary rubber (usually chloroprene rubber) and special rubber (mostly saturated nitrile rubber).They are made of steel cord or glass fiber and are made of rubber or nylon cloth or polyurethane rubber layer.
Introduction of polyurethane V type elastomer
Polyurethane containing many repeated carbamate groups in the polymer backbone (-NHCOO-) polymer, called polyurethane, polyurethane and miscellaneous pieces of international trafficking, as polyurethane, also translated as domestic polyurethane, polyurea urethane etc.;
Polyurethane is a kind of synthetic material which is widely used. Its industrial production is mainly from multi cyanide
And usually containing hydroxy ester polyols prepared by the reaction. The number of different functional groups and different types of functional groups, polyurethane parts manufacturers, using different synthesis processes, can be prepared by different performances, table view of various forms of polyurethane products. There are very soft or hard foam, with elastic rubber wear resistance, high gloss paint, the paint, also has high synthetic fiber synthetic leather for talks, flexural performance, and excellent bonding properties of polyurethane adhesive and so on. Has become the national economy and daily life essential materials, polyurethane elastomer, we are engaged in is a branch of polyurethane materials.
