Technical details for selecting your protection part

From PE to EVA, PP, PA or TPE

Materials

Kiba plastic closures are predominantly made of polyethylene, polypropylene and polyamide, all of which are recyclable hydrocarbons. Thermal recycling of these compounds in approved plants produces the following substances:

water (H2O) and carbon dioxide (CO2) in the case of
polyethylene,
water (H2O), carbon dioxide (CO2) and carbon monoxide
(CO) in the case of polypropylene as well as
water (H2O), carbon dioxide (CO2), carbon monoxide
(CO) and nitrogen (N) in the case of polyamide.
