PPA GF35 Material Overview
PPA GF35 is a black, glass-fiber-reinforced polyphthalamide reference for molded electrical supports, equipment housings and mounting brackets. The WANHAN supplier sheet lists 35% glass fiber. Compare its test results with the part’s wall thickness, fastening loads, moisture exposure and temperature cycle before selecting the offered formulation.

Specimen conditioning is not fully specified for all entries in the reference sheet. These values are not guaranteed specification limits. Confirm the current datasheet, required test conditions and acceptance criteria for your component.
Application Review
Electrical support frames
Define terminal locations, retention forces and minimum wall thickness. Specify the required electrical and flame tests separately; an HB reference does not establish V-0 performance.
Reinforced equipment housings
Review screw bosses, openings and weld lines. Check assembly dimensions after the moisture and temperature exposure expected in service.
Mounting brackets
Identify loaded interfaces and fastening forces. Evaluate stiffness, sustained deflection and fit on a representative molded bracket.
Processing and Part Checks
The supplier’s preliminary guidance lists drying at 110–120°C for 4–6 hours, melt temperature 300–330°C and mold temperature 100–120°C. Treat these as starting references and obtain current instructions for the offered formulation and mold. The HDT row pairs ISO 75-2/B with 1.8 MPa; that designation/load combination requires clarification, so the number is not used as a design value. The impact row pairs an Izod label with ISO 179 and is also omitted. Water absorption has no method stated and is not reproduced as a qualified value.

Material Supply and Manufacturing Support
Nylon Plastic connects engineering plastic supply with custom manufacturing. WANHAN is our cooperating compounding factory; the photographs below show its material-feeding equipment, extrusion process and laboratory.
Grade and formulation selection
Share your current grade, application and operating conditions. We coordinate the material review and identify the matching datasheet for the formulation offered.
Quality documents for your order
Specify the TDS, batch records, inspection requirements or compliance files your purchasing team needs. The documents and acceptance criteria are agreed for the quoted material.
Support beyond resin pellets
For a finished component, connect material selection with part design, tooling and molding review. Start with the drawing, expected quantity and critical dimensions.
Cooperating Factory Management-System Certificates
The supplied ISO 9001, ISO 14001 and ISO 45001 certificates identify Guangdong Wanhan as the certified entity. Their scope concerns modified plastic granules and the related management activities; it does not certify every material grade or every finished-part manufacturing service.
Review manufacturing capabilities and quality documentation. For document approval, match the legal entity, certificate scope and quoted grade.
Frequently Asked Questions
What material does this page cover?
PPA GF35 is a black, glass-fiber-reinforced polyphthalamide reference for molded electrical supports, equipment housings and mounting brackets. The WANHAN supplier sheet lists 35% glass fiber. Compare its test results with the part’s wall thickness, fastening loads, moisture exposure and temperature cycle before selecting the offered formulation.
Does this PPA GF35 reference establish a V-0 flame rating or continuous-use temperature?
No. The sheet lists HB at 1.6 mm, not V-0. Its HDT method/load entry needs clarification and would not establish a continuous-use temperature in any case. Obtain matching thermal and flame evidence for your component.
Are these values a production specification?
No. They are typical reference values for PPA GF35. Agree the current grade, test conditions, acceptance limits and required documents for the order.
Do the images show the exact supplied color and finished parts?
The images illustrate resin appearance and possible component concepts. Confirm color and finish on the offered material and samples; the pictured parts do not establish suitability for your design.
What is required for a material replacement?
Identify the current resin and reason for changing it. Compare exact-grade data, dimensions, loads, temperature and environmental exposure, then validate the intended part before production.
What should I send for a quote or sample request?
Send the reference grade, application, color, estimated material quantity and required documents. For a molded-part inquiry, add the drawing, critical dimensions and acceptance requirements. A CAD file is optional for a material-only inquiry.
