Polyvinyl Acetate PVAC30 (Granules), 1 kg
As the numerical value of the PVAC increases, the degree of polymerisation increases and so does the viscosity of the solution and the durability and tear strength of the film. A low viscosity allows better penetration into the pores, which also results in higher adhesive strength.
Overview:
PVAC 20: better adhesive strength / lower tear strength of the film
PVAC 30: medium tack / medium tear strength of the film
PVAC 50: lower adhesive strength / better tear strength of the film
