Thermoplastics; All our heatshrinkables 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.

Polyolefin tubing are mostly used in assembly stations

Polyolefins begins life as force extruded electrical tubing with a memory built-in; giving the tubing a (thermal) memory. It remembers how they are made, before it is attacked and turned into heat shrink.

Transforming tubing into heatshrink

Transforming the tubing to polyolefin heat shrink, it has to be bombarded with electrical beams through irradiation cross-linking, the insulation is expanded then cooled setting a heat shrink with a built-in thermal-memory.

Heatshrink is like standard tubing, is how I first witnessed this incredible insulation technology. They look like average standard tubing until you started heating it. Heat shrinks can be incredible super flexible, tough, semi-rigid, puncture resistant, or high temperature material that can be used in all markets with low to higher temperatures starting   PVC   |   Layflat   |   Dual wall Adhesive lined   |   LSZH   |   Elastomer   |   PVdF   |   Viton   |   PTFE, 5.2 mm   &   Silicone rubber heat shrink.

Heat shrinks, which type of tubing to use

Heat shrinks and how to use on assembly

Polyolefin heat shrink


Insert the heat shrink tubing over any object to heat shrink it down, best 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.

Military grade EMS3 & EMS4

1) EMS3 Military, are flexible, thin wall, flame retardant operates at -55 to +135C, in colours below.
MIL-DTL-23053/5, VG95343, UL224 VW-1 & CSA 125C OFT. Colours: Black, Clear, Red, Yellow, Green-Yellow, Green, Blue, Grey (Gray) and White. EMS4, 4:1 military over-expanded for cable jacket repairs, to SAE-AMS-DTL-23053/5 class 1 & 3, UL 224 VW-1.

2) 3:1 & 4:1 Adhesive lined (Glue), a dual outer wall tubing, inner adhesive lining, semi-flexible, supplied in thin wall. Specifications: M23053/4, UL224 & CSA. How about a semi-rigid void filler, size 3.2mm? As it is heated over 130C but it fills voids and interstices to encapsulate but its not adhesive lined, called EDW2.

3) Low smoke (LSZH) - flame retardant sleeving so has no added halogens for LS0H thin wall & LSZH 2:1 medium wall, size 19.0mm (3/4 in). Standards: BS4G-198 Part 3, type 15.
