What is HiFill® PPSU

Among engineering plastics, polyphenylsulfone (PPSU) is often the preferred material when strength, heat resistance, and flame retardancy must be combined in one solution. It is widely adopted in medical equipment, aerospace, electronics, and advanced industrial fields. TECHMER PM’s HiFill® PPSU series builds on the well-known benefits of PPSU while offering tailored formulations for different application scenarios.

As an international plastic raw material trader, we comprehensively supply the HiFill® PPSU series of products, helping purchasers quickly find the most suitable material solutions.

01 | Common advantages of the HiFill® PPSU series

Stable flame retardant performance: The entire series meets the UL94 V-0 flame retardant grade and complies with international safety standards.

High mechanical strength: Excellent tensile strength (>60 MPa), flexural strength (85-109 MPa), and flexural modulus as high as 2450 MPa.

Heat Deflection: HDT values of 207–220°C ensure stability in high-temperature applications.

Dimensional & Electrical Reliability: With water absorption rates of only 0.3–0.37% and volume resistivity at 1E15 Ω·cm, the material suits electrical housings and precision parts.

Impact Performance: Izod impact strength can reach 690 J/m, covering applications where toughness is critical.

Quick Selection Guide

  ・PPSU HF NAT → For thin-wall or complex parts where flowability matters most.

  ・PPSU GY061 → For high-impact applications such as connectors or brackets.

  ・PPSU TL10 → PTFE-filled (10%) grade for sliding parts requiring wear resistance.

  ・PPSU A1 0200 B LE → For applications demanding high modulus and strength.

  ・PPSU 4000 BK / NAT → A versatile option balancing mechanical strength and flame retardancy.

04 | Application Recommendations

Medical Devices:

  -PPSU 4000 NAT and HF NAT are suitable for sterilizable parts such as syringe components and ventilator housings.

Electrical & Electronics:

  -PPSU 4000 BK is flame-retardant and used in switchgear, connectors, and plug housings.

High-Impact Parts:

  -PPSU GY061 offers improved toughness, fitting for load-bearing connectors and structural supports.

Friction & Wear:

  -PPSU TL10, with PTFE reinforcement, reduces wear in sliding elements like pump seals or valve seats.

Structural Strength:

  -PPSU A1 0200 B LE is chosen when rigidity and long-term strength are priorities.
