PolyGlobal and ALBIS – Performance Materials Partnership

Posted on: 11th Feb 2019

PolyGlobal is proud to work in partnership with ALBIS, a world leading supplier of thermoplastics. PolyGlobal work closely with ALBIS to offer a range of TPE materials that combine the properties and advantages of thermoplastics with those of elastomers.

Material options include Alfater XL®, Sipolprene® and Evoprene®.

Alfater XL® (TPE-V)

Alfater XL® is a dynamic vulcanized blend of PP and EPDM.  It is ideal for many injection moulding applications, simple or complex, thin walled parts and for use in multi cavity tools.

Alfater XL® has excellent mechanical properties and good durability compared to conventional elastomers. Other characteristics include:

  • Excellent UV, weathering and ozone resistance as well as many aqueous solutions, acids and alkaline mediums.
  • Excellent temperature resistance from -50°C-130°C
  • High melt stability/ high cold flexibility.
  • High hydrolytic resistance & low fogging
  • Good chemical, oil  & heat aging resistance
  • Good wear resistance.

Typical Applications:

Sipolprene ® (TPE-E)

Sipolprene® is a pure polymer belonging to the family of thermoplastic ether-ester elastomers. Its chemical structure allows it to match the characteristics of flexible plastics with the performance of thermoset elastomers. Sipolprene® shows constant mechanical performance over a wide temperature range. Other characteristics include:

  • Very good dynamical load bearing capacity.
  • Good chemical and oil resistance.
  • High temperature resistance from -65°C-150°C
  • High abrasion and wear & scratch resistance.
  • Excellent fatigue, tear and creep resistance.

Typical Applications:

Evoprene® (TPE-S)

Evoprene® is a range of thermoplastic elastomer compounds based on styrene block copolymers such as SBS and SEBS. These compounds have rubber-like properties yet flow like thermoplastics when exposed to heat and pressure. Characteristics include:

  • High hydrolytic resistance.
  • Chemical resistance (ozone and cleaning agents)
  • Excellent weatherability (except SBS) with good low temperature properties.
  • Good flexibility & tear resistance
  • Excellent price-performance ratio.
  • Fully recyclable at all stages.

Typical Applications:

Material Comparison

Evoprene® offers the most price sensitive option followed by Alfate®r and SIpolprene®. Evoprene® and Alfater® have more soft flexible grade options while Sipolprene® has more choice at the rigid end of the spectrum.

Where operating temperature range is a key consideration, Sipolprene® provides the greatest properties , with both a higher top temperature and lower base temperature than the other two options. However, in terms of hydrolytic resistance, Evoprene® and Alfater® would be preferred.

Whilst these materials are from a family of plastics known for good abrasion and wear resistance, if this is the key application concern, Siploprene® would be the recommended option.
