Grade Data for Purchasing
Ask for the current PET GF35 TDS with test methods and conditioning. Mechanical, thermal and flame results must belong to the quoted formulation; values from a different filler level or material grade do not apply.
PET GF35 Applications

Connector and relay housings.
These components need consistent terminal positions, thin-wall molding and accurate assembly. Select a grade that meets the required electrical, thermal and flammability conditions.
Sensor housings and motor end covers.
Check sealing features, bearing seats, fastening points and vibration loads. Validate dimensions and weld lines after molding and conditioning.
Mounting brackets and terminal insulating blocks.
Review bolt loads, terminal retention and the required clearances. Confirm the selected grade with current test data and representative molded parts.
Processing and Part Checks
Use the selected grade’s drying and molding instructions. Check gate position, fiber orientation, weld lines, shrinkage and critical dimensions during trials. Confirm performance on parts made with the intended tool and process.
For finished components, continue to injection molding. For a material comparison, use 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.
PET GF35 — Frequently Asked Questions
What is PET GF35?
PET GF35 is PET reinforced with 35% glass fiber, supplied as pellets for injection molding. Confirm the exact formulation and matching TDS for your project.
Which applications can be considered for PET GF35?
Typical candidates include connector and relay housings, coil supports, terminal blocks, motor end covers and appliance frames. The selected grade must meet the component’s mechanical, thermal and electrical requirements.
Is PET GF35 the same material as PBT GF35?
No. PET and PBT are different polymers. Compare the exact grades’ data and processing instructions, and validate the molded part before considering a substitution.
What drying and molding settings should be used?
Use the quoted PET GF35 grade’s own drying and processing instructions. Do not transfer temperatures or drying times from another PET or PBT formulation. Confirm moisture control and part dimensions during trials.
Does PET GF35 automatically meet a flame-retardant or electrical standard?
No. Glass content does not establish a flame classification or electrical approval. Provide the standard, specimen thickness and service conditions so the formulation and supporting documents can be checked.
What is needed to quote PET GF35?
Send the component application, current material, color, quantity, service conditions and destination. Ask for a matching TDS with test methods; include drawings, critical dimensions and qualification requirements for manufactured parts.
Request Material Data and a Quote
Send the application, current material if available, service temperature, load or fluid exposure, color, expected quantity and delivery destination. Add a drawing when finished parts are needed.
