Polyethylene-terephthalate (PET)

Polyethylene-terephthalate bristles for brushes and brooms

Polyethylene-terephthalate bristles are more and more widely used materials in brush and broom industry due to their big heat resistance and excellent mechanical characteristics. PET regranulate – as end-product of waste processing – is a recycled raw material which can replace PVC since PET is more environment-friendly.

Physical and chemical characteristics

Density: 1,37 – 1,40 g/cm3
Melting point: 245 - 260 ºC
Heat resistance: 70 ºC
Physical state: semicrystalline

Chemical resistance (on 20°C)

Polyethylene-terephthalate resists alkalis and solid acids slightly but to diluted acids, alcohol and organic solvents well.

Fields of application

Household and body-care brushes, brooms, industrial and technical brushes.
