PPO PP ALLOY
product details
The Lightweight Heat Solution — Where mPPO Performance Meets Polypropylene Economy
Material Overview
PPO/PP is one of the more recent additions to the engineering plastic alloy family, and it solves a persistent design problem: engineers who need PPO-class heat resistance and dimensional stability, but who cannot accept its density or cost in mass-produced parts. By compatibilizing PPO with polypropylene’s lightweight, low-cost matrix, this alloy delivers a remarkably balanced property profile.
Densities approach pure PP, with a price structure that opens engineering-grade performance to applications previously priced out of the high-performance polymer market. Renhong’s compatibilizer system uses reactive grafting chemistry to form covalent links between the PPO and PP phases, producing a stable morphology that resists delamination — the failure mode that historically limited adoption of basic PPO/PP blends.
Key Features
🪶 Low Density for Lightweighting
Density as low as 0.95 g/cm³ — among the lighter engineering thermoplastic alloys available.
🔥 High Glow-Wire Performance
Specialty grades achieve GWIT 850–960°C — meeting demanding electrical safety standards.
🌡️ Improved Heat Resistance vs. PP Alone
HDT typically 110–135°C, exceeding pure polypropylene’s thermal envelope.
📐 Better Dimensional Stability than PP
PPO phase reduces shrinkage variability and warp tendency typical of crystalline polyolefins.
💰 Cost-Effective Engineering Solution
Delivers engineering-grade performance at a price point below pure PPO or PA.
