Polyurethane elastomer, also known as PU elastomer or urethane, is a kind of super wear-resistant (commonly known as best of wear-resistance) with good strength, small permanent compression set. A new kind of material between plastic and rubber has the rigidity of plastic and the elasticity of rubber. At...

Polyurethane super grip V belt is widely used in conveying equipment of ceramic tiles, cement tiles, floor tiles, food, wood products, cans, newspapers, prints, glass, etc.   PU super grip V belt produced by our company is developed independently on the basis of the original V belt. It adds...

The mechanical properties of polyurethane elastomers are very good, which are shown in Young's modulus, tensile strength, tear strength and load capacity. Young's modulus and tensile strength are within the elastic limit. The ratio of tensile stress to deformation is called Young's modulus (E) or...

PEPSEN won a bid of polyurethane skid conveyor roller wheel for electric automobile assembly line   Wheel rim: #45 iron, SS314, 40CR, Q235, Wheel tread: Mitsubishi, BASF or BAYER, NDI-formulated polyurethane Hardness: Shore 95A or customized Color: customized color – normal...

RoHS is a mandatory standard regulated by EU legislation, which imposes strict restrictions on toxic and harmful substances in products. All designated products exported to EU countries must obtain certification.   With the development trend of economic globalization and product export, based...

How water and working environment affect polyurethane? Water has two effects on polyurethane elastomers. One is the plasticization of water, that is, water molecules enter into macromolecular chains and form hydrogen bonds with polar groups in polymer molecules, which weakens the interaction...

Generally speaking, the oil resistance of polymers refers to the general oil resistance including solvent resistance, which is in principle adapted to the expansion equilibrium formulation developed by Flory et al. That is to say, only expansion occurs, and only equilibrium of expansion occurs. Chemical...

Polymers have good dielectric properties and are widely used as insulating materials. The physical quantities representing dielectric properties include dielectric constant, dielectric loss (tan_ delta), volume resistivity (p_ v), surface resistivity (p_ s) and breakdown strength (or breakdown voltage)....

What are disadvantages of polyurethane and how Pepsen avoids them? High Temperature and Build-up heat Normal polyurethane can work long time under temperature 80 degree C, work temporarily under 120 degree C. It will also create a build-up heat easily when it is compressed back and forth...

What is the difference between polyether and polyester urethane?   There are many kinds of polyurethane.They can be separated into two main categories as polyester and polyether polyurethane according to variety of polyol. They have their own advantages and disadvantages, so there is no better one...

Polyurethane is well known for its excellent abrasion and impact resistance, so it is usually chose by engineers to use them to stop, support, bearing load, absorb shock and clamp.   However, they can be classified as many kinds though all of them are called polyurethane pad. Based on different...
