Elastomers

Elastomers are engineering materials that can exhibit different behaviours compared to plastics and metals, do not deform in events such as compression or buckling, and can return to their original state by eliminating the force that causes deformation. In addition, it provides low permeability to air, gases, water and steam, provides electrical and thermal insulation, and has good mechanical properties, adhesion to various fibres, metals and hard plastics.

The basic properties of elastomers vary depending on the compositions used in their polymers. For this reason, it is necessary to be sure of the quality of the selected raw materials.

Elastomer

According to the application type of elastomers, there are two methods: hot casting and cold casting. The products obtained can be of different hardness, from very soft to very hard. The hardness is measured by Shore meter device. The hardness related to the A and D scale versions of the device are defined.

When we classify elastomers according to their chemical structure, there are MDI-based elastomers, TDI-based elastomers and aliphatic elastomers. Production and application conditions of each product differ.

Polyurethane elastomers are advantageous materials over rubber, plastic and metals.

Compared with rubber materials: It has advantages such as high abrasion resistance, tear strength, load carrying capacity, oil resistance, ozone resistance, low mold pressure.

Compared with plastic materials: It has the advantages of impact resistance, abrasion resistance, noise reduction, durability, lower mold cost, low temperature resistance.

Compared with metals: It has advantages such as abrasion resistance, durability, corrosion resistance, lightness, noise reduction, insulation.

The areas where elastomers are used most industrially;

  • Skateboard wheels
  • Soles of tennis shoes
  • Aerospace/Transportation  
  • Agriculture
  • Industrial/Mechanical
  • Manufacturing
  • Marine

  • Mining and Quarries
  • Oil & Gas
  • Wheel & Pulley
  • Body Armor
  • Tennis-racquet grip clutches
  • Insulation surrounding speaker
    cables and telephone lines etc.  

 

As PURIN, we offer you products with high hydrolysis resistance, high strength, high tear resistance. For more detailed information, please contact our expert team.

Cold Cast Elastomers

Cold Cast Elastomers

Cold cast polyurethane elastomers are used in a wide variety of applications, from flexible polyurethane resin or foam to very rigid plastics.

TDI Elastomers

TDI Elastomers

TDI Elastomers, a hot cast polyurethane prepolymer, are used in the most demanding applications where high performance is required.


MDI Elastomers

MDI Elastomers

MDI elastomers are designed as two-component or three-component. While these components can be MDI-based prepolymer and short chain polyol components, sometimes they can be mixtures of prepolymer, short chain polyol and long chain polyol.
