Product Overview

PPS + 40% GF (grade PPS JS G8H) is a 40% glass-fibre reinforced polyphenylene sulfide: HDT 263°C (ISO 75, 1.82 MPa, unannealed), tensile strength 140 MPa, flexural modulus 13500 MPa, UL94 V-0 at 1.6 / 2.0 / 3.2 mm, density 1.67 g/cm³. PPS is inherently chemical- and hydrolysis-resistant with stable dimensions; 40% glass fibre further raises stiffness and heat resistance for precision parts running hot, in contact with oils, or requiring flame retardancy.

Typical uses are igniters, solenoid valves and connectors in automotive and industrial equipment. Select against your real temperature, media and wall thickness; send grade, colour, monthly volume and destination for a quote, with samples available for mould trials.

Applications in Detail

Igniters & solenoid valves

HDT 263°C and UL94 V-0 suit positions near combustion or coil heat; PPS resists fuel, engine oil and most solvents, and its dimensions shift little with temperature and humidity, holding fit accuracy for valve cores and ignition mechanisms.

Connectors & automotive electronics

High stiffness, low shrinkage (0.25–0.7%) and V-0 suit thin-wall multi-cavity connectors; dielectric constant 4.5 (1 MHz) and surface resistance 1.00E+14 Ω support electrical insulation. Validate reflow or high-temperature duty against the real temperature profile.

Pump & industrial components

PPS resists hydrolysis and most acids, alkalis and organic solvents, suiting pump housings, impellers and valve parts in hot water, coolant and chemical media. Run compatibility tests before finalising for long-term immersion or strong oxidisers.

Frequently Asked Questions

PPS+40GF or PPS+65% GF/mineral?

40GF offers 10 kJ/m² notched impact and 140 MPa tensile — relatively tougher, for igniters and connectors taking some impact. The 65% GF/mineral grade gives 14000 MPa flexural modulus and HDT 270°C — stiffer and hotter but more brittle (8 kJ/m²), for pump housings and reflectors. Choose by load and temperature.

Does PPS need drying? What melt temperature?

PPS absorbs little moisture, but drying at 130–150°C for 4–6 h is still recommended for surface quality and dimensional stability; melt 280–310°C, mould 120–150°C (higher mould temperature aids crystallinity and stability), upper limit 330°C.

What about flame and chemical resistance?

UL94 V-0 at 1.6 / 2.0 / 3.2 mm; PPS is inherently flame-retardant without halogen additives. It resists fuel, engine oil, coolant and most solvents; strong oxidising acids (e.g. concentrated nitric or sulphuric acid) and hot strong alkalis attack it — run immersion tests for the specific media.
