Applications

Bed Springs

Industry
Consumer goods
Arnitel® TPC is a reliable solution for bed springs as it allows for more design freedom. Due to its high-flow injection moldable viscosity grades, complex designs can be molded easily. It has excellent colorability and color stability. Arnitel has a broad portfolio in shore D hardness (38D-74D), so the parts can be molded in a different stiffness/hardness for different zones of the bed.}

Cosmetic Dispensers

Industry
Consumer goods
Arnitel® is used in Cosmetic Dispensers and has a proven history of use in both food and non-food dispensers with retention of re-spring.}
