`DESIGNERDATA
`
`Thermo plastics
`
`PP
`
`Partly crystalline, a-polar thermoplast with crystalinity between 60% and 70%; in many grades itʼs available,
`pure as well as in blends with fill- and/or re-enforcing additives. Polyolefin, available as homo-, block-co- or
`random-copolymer.
`
`Specific properties
`Mass: 0,895 - 0,92 g//cm3
`Mechanical properties: Relatively sti and tough, also at low temperatures, but depending on the
`crystallinity. Relatively high hardness at low charpy values.
`Very suitable for designing film-hinges.
`
`Physiological properties:
`PP is odourless and tasteless. It is well used in skin contact applications.
`
`Filler and re-enforcing materials
`PP is applied with a lot of filler and re-enforcing materials like chalk, wood dust, glas fiber, long glas fibers,
`glass balls, carbon black. Specially coated fillers in reaction with additives and mineral fillers increase the
`scratch resistance of the PP-surface.
`
`Thermal properties
`Heat resistant to ca. 110ºC. At 0ºC and lower, the material becomes very brittle. When it burns, it smells like a
`candle.
`
`Colour/surface
`The natural colour is milky tranparent to opaque.
`Can be colored in almost any colour, opaque as well as translucent; with high surface gloss.
`
`Processing
`Very well injection mouldable;
`When not pre-treated, badly gluable due to the a-polar surface.
`Good weldable through di erent weld techniques; can be bonded to TPEʼs (2C injection moulding).
`
`Applications
`Due to the fact that the properties are more or less adjustable by the crystallinity, this material is used in a
`wide range of applications.
`A few applications it is used in are:
`packaging's, (bottles, buckets, films), kitchen tools, interiors of refrigerators and washing machines, housings
