HRPP Polypropylene Heat Resistant Compounds For High Temperature Appliance Parts

Heat Resistant Polypropylene Compounds For High Temperature Appliance Parts

Product Description

Heat Resistant Polypropylene (HRPP) compounds are specifically engineered to maintain structural stability and dimensional integrity in environments where continuous exposure to elevated temperatures is required. Unlike standard PP, which tends to deform at temperatures above 100°C, HRPP compounds are modified with heat stabilizers and crystallinity enhancers, enabling them to resist warpage and deformation up to 130–150°C. These materials are widely used in appliance parts such as coffee machine housings, steam iron handles, kettle bases, and microwave oven accessories.

Properties Data Sheet

Precautions

Before processing, ensure the material is pre-dried at 80–90°C for 2–3 hours to avoid moisture-related defects. During product design, avoid sharp edges or thin walls, which can cause stress concentration under high heat. For applications involving direct food contact, select FDA/EU-compliant grades. When used in appliances with metal heating elements, ensure proper clearance to avoid thermal conduction damage.

Features, Advantages & Properties

• Heat resistance up to 150°C continuous use
• High dimensional stability and low warpage
• Excellent electrical insulation for appliance safety
• Lightweight alternative to engineering plastics like PPS or PBT
• Available in natural, black, and custom colors (red, grey, ivory)

Working Principle & Applications

By incorporating stabilizers, antioxidants, and nucleating agents, the crystalline structure of PP is reinforced, enhancing its thermal resistance while retaining toughness. These compounds are ideal for appliance housings, steam-resistant parts, handles, and components near heating zones, where long-term exposure to heat must not compromise mechanical strength.
