METABLEN™ A 3750

METABLEN™ A-3750 is an acrylic-modified polytetrafluoroethylene (PTFE) used as an anti-dripping agent in flame retardant formulations. It can be used for PC and alloy in automotive, aerospace, consumer goods, and electric and electronic applications.BenefitsResins with METABLEN™ A-3750 and flame retardants achieve V-0 in UL-94 testingImproves melt tensionIncreases die swell to improve surface appearanceImproves filler dispersibilityIncreases foam expansion ratioFeaturesAnti-drippingEasy to handleHigher dispersibility than standard PTFE powders*METABLEN™ is provided by Mitsubishi Chemical Corporation, a member of the Mitsubishi Chemical Group.

Features of Modified PTFE

METABLEN A-type can be used as processing aid and anti-dripping agent. It consists of PTFE, modified by acrylic polymer hybrid technology.


METABLEN™ A 3750 - Features of Modified Ptfe

 

  • METABLEN A-type has better handling property than pure PTFE.
  • METABLEN A-type has high dispersibility to matrix resin, and forms fibrillar network structure.
