Characteristics
Shrink ratio: 2:1
Excellent flammability
High temperature resistant to 175℃
USP Class VI material, no heavy metals.
Compatibility with steam(limited cycles), gamma, ETO, and dry-heat sterilization.
Excellent physical and chemical properties
ROHS and REACH compliant
Color
Standard color: Clear, black
Other colors are available upon request.
Operating Temperature Range
Operating temperature: -55℃~175℃
Minimum shrink temperature: 155℃
Minimum fully recovery temperature: 175℃
Approvals
USP Class VI
ISO10993
