Solutions Based on Elastomers

Elastomer is a generic term for elastic polymers. There are thermoplastic elastomers (TPE) and thermosetting elastomers. It is important to select materials appropriately in line with the intended application.

What is an elastomer?

Elastomer is a generic term for polymers that have rubber elasticity at room temperature. There are thermoplastic elastomers (TPE) and thermosetting elastomers. Both types of elastomer have soft segments (flexible phase) for actualizing flexible deformation, hard segments (toughened phase) for actualizing the return to their pre-deformation shape or cross-linking via chemical bonding.

Thermoplastic elastomers (TPE)

The elastomers have a rubber elasticity similar to vulcanized rubber, so the same molding methods used for general resins can be used. It is possible to re-mold them by heating them, and they eliminate the need for a vulcanization process, contributing to an increase in recyclability and a reduction of manufacturing and carbon dioxide emissions.

Thermoset elastomers

The molecular chains of the elastomers bond chemically and maintain fixed points even after heating (irreversible). Generally, they excel in terms of their rubber elasticity, heat aging resistance and weatherability compared to thermoplastic elastomers.

About modifiers

When an elastomer is added as a modifier, it can change the physical properties of polyolefins, engineering plastics, nylons, polyesters, polyurethanes and epoxies. For example, elastomers can provide shock resistance, flexibility and/or sliding properties (slipperiness).

Mitsui Chemicals elastomer-based solutions

Mitsui Chemicals provides the TAFMER™*, ABSORTMER™ and MILASTOMER™ thermoplastic elastomers, the Mitsui EPT™ and FORTIMO™ thermoset elastomers, and the LUCANT™ (liquid) modifier. Both thermoplastic elastomers and thermoset elastomers can be used as modifiers as well. Mitsui Chemicals provides elastomer-based solutions to meet your needs.

Product list

TAFMER™

Non-crystalline or low crystalline α-olefin copolymer that Mitsui Chemicals developed with its unique polymerization technology. It can be used as a resin modifier that dramatically improves the properties of resins and as a flexible and lightweight soft molding material.

ABSORTMER™

An α-olefin copolymer with excellent vibration damping and stress relaxation properties
Different from existing polyolefin in its texture

MILASTOMER™

Olefin thermoplastic elastomers. Their flexibility is similar to vulcanized rubber and they are suitable for various molding methods. They help conserve resources as they are recyclable.

Mitsui EPT™

The first successful domestic production of EPDM (ethylene-propylene-diene terpolymer) in Japan. The product excels in terms of workability, weatherability, ozone resistance, heat resistance, cold resistance, chemical resistance and electrical properties.

FORTIMO™

Existing poly-isocyanates could not actualize anti-yellowing properties while maintaining high elasticity and high heat resistance. The polyurethane elastomer addresses this issue and also actualizes high durability.

LUCANT™

Consisting of ethylene and α-olefin, the co-oligomer is a hydrocarbon-based synthetic oil that does not include any polar groups. The product is additive for materials such as rubbers, resins and paints that provides functionality including workability, flexibility, heat resistance, low-temperature properties, sliding properties, and defoaming properties.
