Elastic Adhesive

PM series

Based on the special silicone modified polymer, Cemedine elastic adhesive series is a multi-function adhesive, featuring robust rubber-like elasticity and adhesiveness over an extensive range. The elastic adhesive uses a combination of flexibility and robustness to solve the problems of "being hard and brittle" found in the conventional adhesives featuring heat resistance and durability, and lack of heat resistance and durability found in soft adhesives such as rubber and vinyl adhesives, thereby making a significant contribution in all industrial arenas.

Features

1.Adhesives formed into rubber-like elastic bodies
  • Absorb external vibration and shock.
  • Absorb thermal strain such as expansion and shrinkage (highly resistant to heat cycle).
  • Have little stress to be concentrated on bonding interfaces.
  • Adhere materials of different types having big differences in linear expansion coefficients.
  • Allow adhesion with substrate having small surface strength (plaster board, calcium silicate board, ALC, etc.).
  • Exhibit great peeling adhesive strength.

 

Torsional free damping elasticity measurement data

The glass transition point of the elastic adhesive (Tg) is -60 degrees Celsius, as shown in the above drawing. Curing film of the elastic adhesive exhibits flexible rubber-like elasticity within -60 to 100°C, a temperature range severer than the general working temperature range for adhesive bondage, bringing about excellent results in various types of bonding characteristics.

2.Adhesive providing stability for all environments

The elastic adhesive featuring flexible and robust elastic film serves to distribute and absorb internal stress, and provides stable adhesive strength in all environmental changes, exhibiting excellent balance.

3.Superb adhesiveness for plastic materials

Epoxy resin elastic adhesives PM165, PM200, PM210 and EP001K provide superb tensile shear strength for plastic materials.
The EP001K has allowed adhesion of the engineering plastics which could not be bonded in the conventional method.
