PEHMA

Poly(2-ethylhexyl methacrylate)

Robust Hydrophobic Polymer

PEHMA is an organic, hydrophobic and non-fouling polymer. It’s synonyms are 2-propionic acid, 2-methyl, 2-ethylhexyl ester, homopolymer; poly(hexyl ethylmethacrylate); polyhexyl ethyl methacrylate. PEHMA is part of the poly(alkyl methacrylate) family and known for:

  • Adhesion
  • Chemical resistance
  • Flexibility
  • Hydrophobicity
  • Weatherability

PEHMA is incredibly robust while remaining flexible, and when pressed into a film at 1.5 micron thickness it allows for >92% visible light transmittance with <1% haze in the visible spectrum.

Product Specifications

PEHMA is offered as a granular solid with <2000 ppm of solvent and <1000 ppm of monomer for research and medical grade applications and can also be supplied as 50% wt solids in cyclohexane for commercial applications.

PEHMA is analyzed through inherent viscosity to meet the following specification range:

Inherent Viscosity (@ 25°C in Toluene) 0.7 – 1.3 dL/g

Should your application require a specific IV range, Polymer Chemistry Innovations can tailor manufacturing to precisely meet your needs.
