Polymer Resins

Polymer resins are available as beads, flakes or powders.

WACKER is a leading manufacturer of polymer resins. Its portfolio comprises poly(vinyl acetates) as well as soluble vinyl chloride co- and terpolymers.

VINNAPAS® PVAc homopolymer grades

Thermoplastic PVAc are marketed under the trade names VINNAPAS®. The portfolio comprises

  • PVAc homopolymers
  • PVAc copolymers of vinyl acetate and crotonic acid
  • Copolymers of vinyl acetate and vinyl laurate

All are available with different molecular weights and solution viscosities.

Main Characteristics

All grades are homogeneous, color-free, odor-free, taste-free and pose no known physiological risk. All VINNAPAS® polymer resin grades (B, C, UW and VL) produce transparent films with excellent adhesion and high gloss.

VINNAPAS® C copolymer grades

Main Benefits

  • Excellent UV stability and abrasion resistance
  • Good aging properties
  • Excellent adhesion to many substrates
  • Clear films with good gloss
  • Solubility in mild, environmentally friendly (HAP-free) solvents
  • Resistance to oil and grease
  • No known physiological risks

VINNAPAS® VL copolymer grades

Main Applications:

  • Low-profile additives for composite applications
  • Solvent-based adhesives
  • Hot-melt adhesives
  • Structural adhesives
  • Coatings
  • Sound-damping sheets
  • Powder injection molding (PIM)

VINNOL® functional grades: M types

WACKER’s vinyl chloride copolymers and terpolymers are marketed under the trade name VINNOL®. The monomer building blocks of these polymers are vinyl chloride and vinyl acetate in different compositions. They are available as:

  • Nonfunctional grades differing in their molar composition and with a broad range of molecular weights
  • Functional grades with carboxyl groups
  • Functional grades with hydroxyl groups

Main Characteristics

All VINNOL® grades are suitable for solvent-borne coating applications and fully compatible with each other. Depending on the grade, they promote excellent adhesion to a variety of substrates.

VINNOL® functional grades: A types

Main Benefits

  • Very good adhesion to plastics and polymeric films of polar character, metal and absorbent substrates
  • High toughness and permanent flexibility
  • Superior abrasion resistance
  • Outstanding water and chemical resistance
  • Inherent flame retardation
  • Excellent solubility and ease of processing

VINNOL® non-functional grades

Main Applications:

  • Heat-sealable coatings for aluminum foil
  • Printing inks and pigment preparation
  • Industrial coatings
  • Adhesives
