PP TD20 Material Overview
PP TD20 is a black polypropylene formulation referenced to the WANHAN supplier sheet dated 24 August 2022. For molded covers, interior supports and mounting parts, compare the measured data with the part’s loads, temperature exposure and assembly dimensions. The sheet separates specification requirements from WANHAN results; the figures below use the WANHAN column.

Application Review

Molded covers
Check mounting holes, rib transitions and cosmetic surfaces. Agree the black color reference on a molded sample before approving production.
Interior support components
Define the mating interfaces and sustained load. Compare dimensional movement and assembly fit under the expected temperature cycle.
Mounting parts
Specify fastener loads and critical locating dimensions. Evaluate the offered formulation in a representative assembly.
Processing and Part Checks
Request the current PP TD20 processing instructions before a trial. The original sheet does not provide a complete barrel-temperature or mold-temperature window. The Izod row pairs ASTM D256 with kJ/m², so its result is held for clarification. Ash content is not used to infer an exact talc content. This page does not establish a flame-retardant rating or an automotive approval.

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?
PP TD20 is a black polypropylene formulation referenced to the WANHAN supplier sheet dated 24 August 2022. For molded covers, interior supports and mounting parts, compare the measured data with the part’s loads, temperature exposure and assembly dimensions. The sheet separates specification requirements from WANHAN results; the figures below use the WANHAN column.
Which column is used for the PP TD20 property values?
The table uses the supplier’s WANHAN measured-results column. The separate Spec column contains requirement limits and is not presented as a second measured formulation. These reference results are not guaranteed production limits.
Are these values a production specification?
No. They are typical reference values for PP TD20. 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.
