Polyolefin heat shrink, PVC, LSZH, Elastomer, Kynar, PVdF, Viton & PTFE


All thermoplastics; Polyolefin, LSZH, Kynar, Elastomer, Viton & PTFE have a (thermal) memory point when they're caused to extend beyond such (thermal) memory point. They remain dimensionally stable only for an unknown indeterminate length of time, dependent upon the temperature to which the material is subjected.

Mostly used polyolefin tubing

Polyolefin begins life as force extruded electrical tubing with a memory built-in; giving the tubing a memory. It remembers how it was made.

Transforming polyolefins into heat shrink

Transforming the tubing into a polyolefin heat shrink, it's bombarded with electrical beams through irradiation cross-linking, the insulation is expanded and cooled thus producing a heat shrink tubing with a built-in thermal-memory.

Polyolefin heat shrink is like standard tubing, is how I first witnessed this incredible heat shrink technology. Polyolefins look like 'bog standard tubing' until you started heating it. Heat shrink can be incredible super flexible, tough, semi rigid or high temperature material that can be used in all markets with low to higher temperatures starting   PVC   |   Layflat   |   Polyolefin   |   LSZH   |   Elastomer   |   PVdF  |   Viton   |   PTFE   &   Silicone Rubber.

Polyolefin heat shrink, which type to use

Polyolefin heat shrink tubing







 

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


Heat shrinks and how to use on assembly

Polyolefin heat shrink


 

Heat shrink tubing, insert over any object and ready to heat shrink it down, the best guide is to always heat from the middle working outwards so the heat shrink grips the middle area to avoid slipping and gradually proceed to one end and then from the middle again to the opposite end, this avoids cold air being trapped under the tubing or sleeving.

Some clear polyolefins don't require a heating source but can shrink down by inserting into hot boiling water (100C).

Polyolefin heat shrink, adhesive lined or LSZH

1) Polyolefin heatshrinks are flexible, thin wall, flame retardant operates at -55 to +135C, 2:1 Polyolefin & LS0H.

2) Heat shrink 3:1 & 4:1 Adhesive lined (Glue), a polyolefin dual outer wall tubing, adhesive lining, semi-flexible, supplied in thin wall.

3) Heat shrink low smoke (LSZH) - polyolefin flame retardant sleeving so has no added halogens for LS0H thin wall & LSZH medium wall.

Non polyolefins; PVC, Layflats, Elastomer, Kynar, Viton, PTFE.

Heat shrink sleeving PVC 2:1

2:1 PVC heat shrink tubing, general purpose, thin wall, UL is ideal for electrical busbar distribution centres, handles, ropes, chain applications. HST (PVC) sizes from 3.2mm to 102mm.

Elastomer heat shrink tubing 2:1

Elastomer cross-linked, flexible, designed for areas that needs oil & diesel protection & abuse at high temperatures. Elastomer sizes 3.2mm to 76.2mm.

Heat shrink tubing Kynar (PVdF) 2to1

Kynar, 2:1 a super thin wall, super tough, chemical resistant, semi rigid polymer. Kynar or PVdF sizes 1.2mm to 25.4mmm.

Heat shrink viton & viton-plus

Viton heat shrink 2:1, a co-polymer of vinylidene-hexafluoro-propylene, a premium grade heatshrink withstands any chemical attack, they are oil and diesel resistant. Viton sizes from 3.2 to 50.8mm. Special colours are upon request for 3.2mm to 25.4mm.

Heat shrink viton-plus is exactly as previous viton but with added temperature of 10% more than standard viton. Viton plus sizes from 3.2 to 50.8mm.

PTFE heat shrink tubing

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

PTFE sizes for 4:1 from 3.2mm to 32.0mm.
PTFE sizes for 2:1 from 1.27mm to 23.6mm.
