Heat shrink like standard
tubing until you heat it up

Heat shrink like standard tubing until you heat it up - when I first saw this material back in 1987, it was just tubing, standard tubing until you start heating it's properties and magic begins, an incredible flexible, tough, semi rigid or high temperature material that can be used in all market industries with varying temperatures from PVC, Polyolefin, LSOH, Elastomer, Kynar, Viton, PTFE & Silicone Rubber products.

Heat shrink tubing, which type 2:1, 3:1 or 4:1

Heat shrink tubing

Which type 2:1, 3:1 or 4:1 heat shrink tubing to use, these shrink polymers comes in an varied temperature and forms of flexibility polymers in PVC | Polyolefin| Polyolefin Low Smoke | Polyolefin Adhesive lined | Elastomer | Kynar | Viton | Silicone Rubber & PTFE.

The higher the operational temperature equates to higher the costs for that particular polymer products for heat shrink tubing.

Silicone Rubber heatshrink sleeving has a 1.7:1 special with lead time conditions and set minimums as not a standard issue, so if looking for silicone rubber sleeving please get in touch.

Heat shrink in varying temperatures

2:1 Heat shrink Layflat PVC, -20 to +85C

2:1 Heat shrink PVC -30 to +105C

3:1 & 4:1 Polyolefin, Adhesive lined, -55 to +110C

2:1 & 3:1 Polyolefin, -55C to +135C

2:1 & 3:1 Low Smoke - LSOH, -55 to +125C

2:1 Elastomer heat shrink, -75 to +150C

2:1 Kynar heat shrink, -55 to +175C

2:1 Viton heat shrink, -55 to +200C

2:1 Viton+ heat shrink, -55 to +220C

4:1 PTFE heat shrink, -70C to +260C

1.7:1 Silicone Rubber heat shrink, -75C to +250C

Polyolefin heat shrink tubingWhen heat shrinking down, the best guide is to always start from the middle working outwards so the polymer grips the middle area to avoid slipping and gradually proceed to one end and then from the middle again to the opposite end, which avoids air being trapped under the tubing or sleeving.

2:1 & 3:1 Polyolefin heat shrink

Polyolefin, flexible, thin wall, flame retardant
operates at -55 to +135C.
2:1 and 3:1 Polyolefin (2:1 EMS2, 1.2 to 152mm)
(3:1 EMS3, 1.5/0.5mm to 40/13mm)

3:1 & 4:1 Adhesive (Glue) lined shrink

Polyolefin tube, dual wall inner adhesive
(glue) lining, semi flexible, supplied in thin wall.
3:1 and 4:1 Adhesive lined 3mm to 52mm (htat)

2:1 LSZH Low Smoke Heatshrink

LSZH Polyolefin flame retardant sleeving so has no added halogens for LSOH Thin wall & LSZH medium wall.
2:1 LSOH & LSZH, ID 1.2 to 102mm

Non Polyolefin - PVC, Elastomer, Kynar, Viton, PTFE Polymers

2:1 PVC, -30 to +105C

2:1 PVC Sleeving, General purpose, thin wall, UL is ideal for electrical busbar distribution centres, handles,
ropes, chain applications.
2:1 PVC - 3.2 to 101.6mm

2:1 Elastomer Heat Shrink Sleeving

-75 to +150C, 2:1 Elastomer Cross-linked, flexible, designed for areas that needs protection against abuse at high temperatures.
2:1 Elastomer, 3.2 to 76.2mm

2:1 Kynar (PVdF) Heat shrink

2:1 Kynar, a super thin wall, super tough, chemical
resistant, semi rigid polymer.
2:1 Kynar, 1.2 to 25.4mmm, non standard 1.5" & 2.0"

2:1 Viton Heatshrink

Co-polymer of Vinylidene & Hexafluoro
propylene, Viton a premium grade, withstands chemical
attack, oil and diesel resistant.
2:1 +200C Viton, 3.2 to 50.8mm

2:1 Viton+ heat shrink tubing

Viton+ Heat Shrink Viton plus as exactly as previous Viton
but with added temperature of 10% more than
standard Viton. 2:1 +220C Viton +, 3.2 to 50.8mm

2:1 & 4:1 PTFE heatshrink tubing

2:1 & 4:1 are used in highly critical & extreme
environments due to it being the highest temperature
in all polymers, 2:1 and 4:1 PTFE
