Product Overview
PPS + 65% GF (grade PPS JS B105 BK) is a 65% glass-fibre/mineral reinforced polyphenylene sulfide in black: HDT 270°C (ISO 75, 1.82 MPa, unannealed), tensile strength 160 MPa, flexural modulus 14000 MPa, UL94 V-0 at 1.6 / 2.0 / 3.2 mm, density 1.96 g/cm³. The high loading gives very high stiffness and heat resistance with low shrinkage (0.2–0.5%) and stable dimensions, suiting structural parts carrying higher loads at high temperature with low warpage.
The high filler content makes it relatively brittle (notched impact 8 kJ/m²), so it is not for high-impact or repeated snap-fit locations. Typical uses are pump housings, lamp components and reflectors. Send grade, colour, monthly volume and destination for a quote; samples are available for mould trials.
Applications in Detail
Pump housings & fluid parts
14000 MPa flexural modulus and HDT 270°C keep pump housings in shape under high temperature and pressure; PPS resists hydrolysis, coolant and most chemicals, and low water absorption keeps dimensions stable in hot-humid service. Validate pressure parts at the real pressure and media.
Lamp parts & reflectors
HDT 270°C withstands the high temperature inside lamps near the light source; low shrinkage and warpage hold reflector surface accuracy and assembly gaps. The black grade suits light-blocking structures; for reflective surfaces confirm the surface treatment or choose a light-colour/platable grade.
High-rigidity structural parts
160 MPa tensile and 14000 MPa flexural modulus suit replacing some metal brackets, frames and under-hood peripherals, cutting weight while keeping stiffness. Note notched impact is only 8 kJ/m² — avoid sharp-corner stress concentration and drop loads; switch to 40GF or a toughened grade where needed.
Frequently Asked Questions
Is the 65% glass fibre or mineral? What split?
The supplier sheet states 65% filled PPS (glass/mineral composite) without giving the exact glass-to-mineral split. This page follows the supplier wording as a glass/mineral composite; for an exact ratio for tooling or certification, request the grade's formulation note from us.
Why is impact only 8 kJ/m²? Is it too brittle?
The 65% loading pushes stiffness and heat resistance very high at the cost of toughness — a normal trade-off for highly filled PPS. It suits stiffness/heat-led parts without strong impact; for drops, snap-fits or vibration impact choose 40GF (10 kJ/m²) or a toughened grade and validate on the finished part.
How should processing and drying be set?
Dry at 130–150°C for 4–6 h, melt 280–310°C, mould 120–150°C, back pressure 0.2–5 MPa, moderate-to-fast injection, upper limit 330°C. Highly filled material is abrasive — use a wear-resistant screw and barrel, and tune gates and venting to the part.
