All Thermoplastics have a (thermal) memory point when they're caused to extend beyond such (thermal) memory point. They do remain dimensionally stable only for an unknown indeterminate length of time, dependent upon the temperature to which the material is subjected.

Polyolefins are mostly used in factory assembly stations

They begin life as a force extruded electrical tubing. giving the tubing a (thermal) memory. Olefins remembers how they're made, before it is bombarded and transformed into it.

Transforming the tubing

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

Heat shrink tubing in white is like standard tubing, is how I first witnessed this incredible white insulation technology. They look like average standard tubes until you started heating it. They 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   |   Lay flat   |   Dual wall Adhesive lined   |   LSZH   |   Elastomer   |   PVdF   |   Viton   |   PTFE, 5.2 mm   &   Silicone rubber.

Heat shrinks and how to use on assembly

Polyolefin heat shrink


An example: Insert the heat shrink over the fence post. Apply circular rotating flame from the middle of the fence post insulation working outwards so the insulation material recovers and grips the middle area to avoid slipping and gradually proceed to one end and then from the middle again to the opposite end to get that tight insulation fitting. The same method applies to gamma grip enlargers, see image below.

Military grades EMS3 (example 9/3-9 White) & EMS2 25.4 in yellow

1) EMS3 Military, are flexible, thin wall, in white, 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 striped earthing, 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 SCL 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, ENH1 19.1. Standards: BS4G-198 Part 3, type 15.

Others, PVC, Layflats, Elastomer, Kynar, Viton, PTFE.

PVC 2:1, UL 224
