Youli Glue Spring Glue Polyurethane Elastomer PU Rod Shaft Sheet Roll

Product Description

PU: thermosetting polyurethane elastomer for short PU, English name Casting Polyurethane, commonly known as Youli glue, spring glue, is made up of polymer polyol and different Cyanate ester reaction, chain extension, a new synthetic material between plastic and rubber.
According to the different backbone structure of polyurethane elastomer, it is divided into polyether Type and Yukalac type of two kinds
Polyether-type PU rod: English name Polyether urethane. Polyether-type polyurethane occupies the main role in polyurethane, mainly because of the polyether viscosity Small and easy to operate. Polyether is better than polyester in its resilience, moisture evaporation, low temperature performance, impact strength, heat accumulation, water resistance and mold resistance .
Polyester PU rod: English name Polyester polyurethane, compared with polyether, mechanical strength, tensile strength, tear strength, sliding friction, resistance Oil properties, thermal aging, metal adhesion, solvent resistance and oxidation resistance are better than the polyether type. However, the polyester viscosity is large, and the operation is more difficult.
Characteristics: PU rod has chemical corrosion resistance, tensile strength, high elasticity, high pressure load resistance, high wear strength, strong shock absorption, tear resistance, radiation resistance, high strength, High bearing and shock oning and other good performance. High elasticity can be maintained in a wide hardness range (Shaw A10 to Shaw D75). Its excellent and unique comprehensive performance It is not available with ordinary plastic and rubber.
Application field: suitable for metallurgy, mining, petroleum, automobile, building materials, sports, heavy machinery, large stamping equipment damping pad, pad, spring, and do a variety of punching die of metal plate and pipe. Universal mechanical equipment friction, cushioning or shock absorption, is ideal for mold spring
