Printashrink SPF3

Printashrink SPF is a 3:1 shrink ratio heatshrink polyolefin with a working temperature of 135°C. It is a UL approved, fire retardant sleeve which meets MIL-SPEC requirements making it perfect for aerospace, military, defence and other professional applications. It is available in several colours and sizes up to 39mm ID and can be cut and printed as required.

This flexible 3:1 heatshrink polyolefin sleeve with a 135°C working temperature is perfect to cover irregular pieces or pass over larger components in situations where MIL-SPEC and/or UL approval is necessary or favourable. It is used in many industries including military/defence, aerospace, electrical, electronic and automotive sectors and is valued for its insulation, mechanical protection and strain relief properties for commercial applications. The higher shrink ratio also allows any one supplied diameter to fit a greater range of different sized applications. We offer our full range of printing and cutting services on this high quality, commercial sleeve making it perfect for identification, branding and marking requirements.
