High Strength Glass Fiber Reinforced PP Granules For Appliance Housings

Product Description

High Strength Glass Fiber Reinforced Polypropylene (PP) granules are designed to deliver outstanding rigidity, impact strength, and dimensional stability for demanding appliance housings. By incorporating 20–40% glass fibers into the polypropylene matrix, this engineering material significantly enhances its load-bearing capacity, ensuring long-lasting performance in electrical and household appliances. The granules are widely used in washing machines, air conditioners, microwave ovens, and vacuum cleaners where durability and mechanical safety are essential.

Properties Data Sheet

Notes: The general guidelines are only for reference. Exact settings have to follow the product and machine conditions.

Avoid contact with other materials, dust and debris in the injection processing.

Avoid long time stay in the barrel in the injection processing.

Precautions

Before processing, the granules should be dried at 80–90°C for 2–3 hours to avoid surface defects caused by moisture absorption. Mold design should account for shrinkage rates between 0.5–0.7%, which are lower than unfilled PP. Avoid long-term UV exposure unless UV-stabilized grades are used. For appliance housings that come in direct contact with food, FDA-compliant versions are available.

Features, Advantages & Properties

• Tensile strength up to 80 MPa with glass fiber reinforcement

• Excellent dimensional stability for precision housings

• Superior impact resistance compared to standard PP

• Heat deflection temperature up to 140°C

• Available in black, natural, grey, or customized colors

• Lightweight compared to metals, reducing overall appliance weight

Working Principle & Applications

The glass fibers act as reinforcing agents within the polymer matrix, distributing mechanical stress and preventing deformation under load. This synergistic reinforcement makes the material ideal for washing machine covers, air conditioner housings, vacuum cleaner shells, and small appliance casings. With its balance of strength and cost efficiency, it is widely adopted in both household and industrial appliances.
