FAQ

Can Modified PP Black CP323 replace the grade we are using now?

Yes. Send us the incumbent grade and the critical values (tensile strength, impact at −30 °C, shrinkage, colour) and we match the formulation to those targets. Most customers validate with a 5–25 kg sample before switching production.

Why can two compounds with the same grade name differ by 15% in strength?

Fibre length retention and the coupling system. We control shear on twin-screw lines and test every lot for MFR, ash, tensile and impact; each lot ships with a COA for traceability.

What are the typical properties of Modified PP Black CP323?

What is Modified PP Black CP323 typically used for?
Modified PP Black CP323 is typically used in:Injection moulded parts、Appliance internals、Industrial fittings
What is the minimum order quantity for Modified PP Black CP323?
Minimum order quantity is 500 kg for standard grades and 1 tonne for newly developed custom formulations.
Can Modified PP Black CP323 be tailored to specific performance targets?
Yes. Qingdao Yunsu adjusts formulations to the target requirements, including glass fibre loading, flame-retardant class, UV and weathering resistance, antistatic or conductive properties and colour, and supports dedicated grade development.
How long do sampling and mass production take?
Sampling takes 3-7 days for existing grades and 7-15 days for new formulations; mass production runs 10-20 days after sample approval, shipping from Qingdao Port.
