Reference: the supplier WH-GF30A sheet dated 25 August 2022. These are reference test values, not a current supply guarantee or finished-part specification. Confirm the latest revision, conditioning and test requirements. The sheet’s HB listing is not a V-0 qualification, and HDT is not a continuous operating-temperature limit.
PPA GF30 Applications
Gears and transmission components.
Spur, bevel and worm-gear candidates need a review of tooth geometry, torque, speed, mating material and lubrication. Validate wear, noise and dimensions on parts made with the selected formulation.
Bearing cages, bushings and guide rollers.
Specify contact pressure, speed, counterface, clearance and lubrication. Check friction, wear and sustained-load behavior rather than selecting the grade from tensile strength alone.
Pump impellers, housings and covers.
Provide the fluid, temperature, pressure and duty cycle. Review ports, weld lines, fasteners and sealing dimensions, then confirm compatibility and performance through the agreed part trials.
Processing and Part Checks
Request the current WH-GF30A drying and processing instructions. Review glass-fiber orientation, weld lines, shrinkage and the intended thermal cycle. Validate critical dimensions and performance under the actual loads, contact conditions and fluids.
For finished components, continue to injection molding. To compare material families, review the engineering plastics range.
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 is PPA GF30?
It is polyphthalamide reinforced with 30% glass fiber. The supplied reference document identifies this natural-color compound as PPA WH-GF30A.
Which applications are listed for WH-GF30A?
The supplier sheet lists gears, bearings and pump parts. Specific gear types, bearing components and pump designs still need a review of loads, speed, temperature, lubrication and fluid exposure.
How current is the available datasheet?
The supplied WH-GF30A sheet is dated 25 August 2022. It is provided as a dated reference; request the current revision and confirm the exact production formulation before approval or purchase.
Does the 300°C HDT mean continuous use at 300°C?
No. It is a deflection result under ISO 75-2/A at 1.82 MPa. Continuous heat exposure, creep, aging and part geometry require their own engineering assessment.
Is this PPA GF30 a V-0 flame-retardant grade?
The available sheet lists HB and does not establish V-0 qualification. If a flame rating is required, specify the standard and thickness and request a matching formulation and report.
What is needed for a material quote?
Send the drawing or application, load and speed, operating temperature, fluid and lubrication conditions, color, quantity, destination and required documents. State the current material if the project involves substitution.
Request Material Data and a Quote
Send your application or drawing, current grade, service conditions, color, quantity and destination. Include required test methods, documents and acceptance criteria so the offered material can be evaluated against the project.
