Reference Material Properties
Reference grade: PP WH2500A. Values apply to the stated supplier reference, not every formulation in the material family.
| Property | Typical value | Unit | Test method |
|---|---|---|---|
| Tensile strength | 35 | MPa | ISO 527 |
| Tensile elongation at break | 65 | % | ISO 527 |
| Flexural strength | 50 | MPa | ISO 178 |
| Flexural modulus | 1500 | MPa | ISO 178 |
| Izod notched impact strength | 10 | kJ/m² | ISO 180 |
Typical values are taken from the supplied PP WH2500A reference sheet. Conditioning and flame-test thickness are not stated. Melt-flow settings must be confirmed with temperature and load before comparison or process planning.
PP FR Applications
Terminal blocks, plugs and socket bodies.
Review terminal retention, assembly forces, wall thickness and the required electrical clearances. Agree the grade and supporting flame record for the component.
Connector and control housings.
High-flow grades can be evaluated for ribs, thin sections and complex cavities. Confirm filling, weld lines, impact areas and dimensions with the intended mold.
Junction boxes and appliance electrical parts.
Check cable entry, screw bosses, cover fit and the actual service environment. Outdoor or UV exposure, heat aging and enclosure ratings need their own qualification.
Processing and Part Checks
Match the mold and process window to the confirmed PP WH2500A formulation. Check filling, weld lines, shrinkage, snap features and fastener areas during trials. Follow supplier processing guidance and agree the required part and flame tests before production.
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 PP WH2500A?
It is the supplier reference for a high-flow flame-retardant polypropylene compound supplied as injection-molding pellets. The product record also writes the code as PP-WH2500A.
Which components can use this flame-retardant PP?
Terminal blocks, connector bodies, control and circuit-breaker housings, plugs, sockets, appliance electrical parts and junction boxes are candidates. Suitability depends on the selected formulation and component requirements.
Is every color and wall thickness covered by a V-0 claim?
No. The reference sheet lists V-0 without a test thickness. Confirm the formulation, color, thickness and applicable test record; do not transfer a result from a different grade or specimen.
Can the published melt-flow value be used on its own?
No. A melt-flow comparison needs the temperature, load and test method. Ask for the current TDS and the processing window rather than choosing molding settings from a flow number alone.
Can this PP replace flame-retardant nylon or PC/ABS directly?
It should not be treated as a direct substitute without validation. Compare temperature, stiffness, impact, creep, shrinkage and electrical or flame requirements for the exact grades, then assess the molded component.
What information is needed for a quote or sample request?
Send the part application, drawing if available, thickness, required standards, service conditions, color, quantity and destination. Note any current resin and the reason for changing it.
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.
