Modified PPS: What Buyers Need to Know in 2025


Modified PPS (Polyphenylene Sulfide) is a high-performance engineering plastic widely used in industries requiring durability and heat resistance. This article explores its types, functions, and how to source it effectively.


How to Find Reliable Modified PPS from China in 2025


China remains a top supplier of Modified PPS, but buyers must verify certifications like ISO 9001 and RoHS. Look for suppliers with proven track records on platforms like Alibaba. Request samples to test quality before bulk orders.


What Buyers Should Know Before Buying Modified PPS from China


Key considerations include lead times (typically 4-8 weeks), MOQs (often 500kg+), and payment terms (30% deposit). Ensure suppliers provide material data sheets (MDS) for verification.


Types of Modified PPS


1. Glass-Fiber Reinforced: 40% higher tensile strength
2. Mineral-Filled: Improved dimensional stability
3. Impact-Modified: Enhanced toughness for automotive parts


Functions and features of Modified PPS


• Heat resistance up to 220°C
• Chemical resistance to fuels/solvents
• UL94 V-0 flame rating
• Low moisture absorption (0.02%)


Scenarios of Modified PPS


Automotive: Fuel system components
Electronics: SMT components
Industrial: Pump housings
Medical: Sterilizable equipment


How to Choose Modified PPS


1. Define operating environment (temperature/chemical exposure)
2. Verify mechanical property requirements
3. Check color stability needs
4. Compare prices from 3+ suppliers
