Covering Transparent PP PC PVC Insulation And Protection
PP(polypropylene) sheet is known for its excellent chemical resistance in corrosive environments, and very good abrasion resistance.
They have good property of isolation, light weight, mechanical strength, resisting electric arc, oil and heat. Some can withstand 120℃. Some fire-retardant products pass UL-V0 test.
These mylars, often combine with double-sided adhesive tape, stick to somewhere needed to insulate. Or use screw to fix via small holes in it.
Basic mylar properties:
No. | Item | requirement | test data |
1 | thickness | 0.1-0.5mm | ±0.2 |
2 | density g/cm3 | 1.3-1.5 | 1.32 |
3 | tensile strength | ≥44 | 50.6 |
4 | ball-fall breakage % | no break | no break |
5 | Vicat softening point | ≥55℃ | 60℃ |
