Long glass fibre reinforced PP
Adding glass fibre to polypropylene (PP) significantly enhances the mechanical properties of the thermoplastic, such as tensile strength and compressive strength. Long glass fibre reinforced PP / long glass fibre filled PP is also affordable, sustainable, and easy to recycle. The material is also extremely suitable for redesigning metals or other technical materials. This makes it possible to achieve savings and develop alternative lightweight products and technical shaped components.
Long glass fibre reinforced PP
Long glass fibre reinforced PP / long glass fibre filled PP is regularly used for injection moulding of large shaped components, products and housings made of plastic. In fact, glass fibres are the type of fibres used most frequently in reinforced polymers. This material is used for such purposes as producing a high-quality finished product that is easy to clean, requires UV resistance, and has good thermal properties. Other advantages include:
- High modulus of elasticity
- Low density
- High strength
- Long-lasting resistance to thermal ageing
- Increased toughness
- Beautiful surface finish
Injection moulding with long glass fibres
The initial length of the long glass fibres is somewhat limited during processing in an injection moulding machine, due to the size of the pellets (generally 10 mm – 25 mm).
In the first stage, during plasticisation, the fibres are subjected to extreme force. This is because the softened substrate is not yet fully melted at that point.
Flow resistance gradually decreases during the melting process. After the mixture is fully melted, the substance is injected into the mould.
Factors that are taken into account when processing long glass fibre PP include the configuration of the injection screw assembly and the non-return valve. Find out more about the injection moulding cycle of plastic products here.
When can fibre glass reinforced PP be used?
Wondering when fibre glass reinforced PP is used? Its mechanical properties make it possible to use this material in a wide range of applications and in various market segments. For example, this technical plastic is found in vehicles, or in agricultural applications such as:
- Instrument panels
- Front-end components and
- Base-plate components
It is also used to replace metals or other technical materials with lightweight materials. Would you like to know whether your product, shaped component or housing can be redesigned? Request a QuickScan and receive a quick answer about the possibilities and an initial estimate of the costs.
