Medical thermoplastic elastomers
Zelas Zelas™ TPO

ABOUT

Zelas™ is a functional resin compound designed for medical device and pharmaceutical packaging.
A styrene-based elastomer type (TPS) with good rubber elasticity and sealing properties.
Olefin-based elastomer type (TPO) using a unique reactor TPO,
There is an amorphous olefin type (CP) that offers high transparency and low adsorption performance.
We also carry medical-grade polyurethane manufactured in the United States.

Features of Zelas™ TPO

■Resin Products: Medical-grade compounds (Zelas™) are used for packaging medical devices and pharmaceuticals.
It is formulated with a specific blend in mind.

■Zelas™ has high drug hygiene properties and is used as a material for pharmaceutical packaging and medication dispensing devices.
It has been in use for many years.

■Olefin-based elastomer type Zelas™TPO is based on our proprietary reactor TPO,
We offer grades suitable for each layer of medical soft bags: the inner layer, the middle layer/adhesive layer, and the outer layer.
