Product Name:

Melthene®-H

Generic Name: Saponified ethylene vinyl acetate copolymer
Chemical Formula / Diagram: Chemical-structure---Melthene-H.png
Product Overview: Melthene-H is a ternary copolymer with ethylene, vinyl acetate, and vinyl alcohol units. It can be mainly used as a modifier for polar polymers, processing aids, lubricants and adhesive agents, and complies with various food contact requirements. Please contact us for further details.
Applications:

Modifier and compatibilizer

H6051K can modify mechanical, recycling, flexible and adhesive properties for polar polymers. It shows excellent performance as a compatibilizer between polyolefins and polar polymers.

Examples of polymers that can be modified

  • Ethylene-vinyl alcohol copolymer (EVOH)
  • Polyamide (PA6, PA66, etc.)
  • Polyesters (PBT, PETG, PET, etc.)
  • Polyolefins (PE, EVA, PP, etc.)

Processing aid and lubricant

H6822X functions to enhance the flowability of polymers. Polymers with H6822X can prevent long-time residence of the polymer in an extruder (Figure 1). It is expected to reduce contamination such as gel into product, and reduce frequency of thorough cleaning.

Adhesives

H6410M has good adhesion to metal, polymer, glass, paper, and fabrics (Figure 2). It can be used in general molding and processing machines.
