Features

Ca-Zn has taken the place of lead-based stabilisers in outdoor products and in uses that touch food. It offers heat stability, clarity and processability, with good electrical properties. With more than 30 years of developing and making Ca-Zn stabilisers in Japan, we propose grades for demanding uses such as food-wrap film, wire coating and automotive leather.

Main uses

Food wrap
Toys
Medical devices
Wire insulation
PVC leather
Car interior trim
