Material systems
Six modified plastics series
From base resin to finished compound. Every series has established production grades, and every grade can be tailored to your performance specification.
Modified Nylon (PA6 / PA66)
High strength, stiffness and wear resistance. Glass fibre reinforcement lifts it to load-bearing structural parts, replacing metal.
View PA series →Modified Polycarbonate
High impact strength, dimensional stability and clarity. Flame retardant and low-temperature grades for electrical parts.
View PC series →Modified ABS
Balanced properties, easy processing and good surface finish. Weather resistant and anti-static versions for outdoor and precision equipment.
View ABS series →PC/ABS Alloy
Combines the impact and heat resistance of PC with the processing and cost profile of ABS — the mainstream choice for appliance housings.
View PC/ABS series →Polyphenylene Sulfide
Inherently flame retardant, high temperature resistance, dimensional stability and chemical resistance for demanding industrial parts.
View PPS series →
Select by application
Find the material by what you mould

Our plant
Own production base, extrusion lines and testing laboratory
Qingdao Yunsu Polymer Material Technology Co., Ltd. (CPlastics) was founded in 2016 and specialises in the R&D, production, sales and service of high-performance modified engineering plastics. The plant covers 15,000 m² in the Jimo District of Qingdao, China. We formulate in-house, control our own production and test our own material — the basis of consistent lead times and batch-to-batch reliability.

Why CPlastics
Why work with us
Our service model is built around the practical problems injection moulders face, from formulation to volume delivery.
01
Formulated to your target
Give us the working conditions, performance targets and cost ceiling — we design the formulation backwards from there, rather than pushing an off-the-shelf grade.
02
3-7 day sampling
Samples of existing grades in 3-7 days and new formulations in 7-15 days, shortening your mould trial and validation cycle.
03
Replacement for the grade you run now
We benchmark against the grade you run today, validate it through small-batch mould trials, then phase it in to reduce material cost.
04
Documents with every batch
TDS and COA supplied as standard, UL94 yellow cards for flame retardant grades, and PPAP documentation for automotive grades.
05
Low minimum order
From 500 kg for established grades and 1 tonne for new formulations, keeping your trial and inventory risk low.
06
Export experience
Familiar with the certification, packaging and customs requirements of buyers across Asia, Europe, the Americas, the Middle East and Africa. Customer-nominated forwarders welcome.

FAQ
Questions buyers ask before ordering
What modified engineering plastics can CPlastics customise?
We compound six base systems: PP (polypropylene), PA6/PA66 (nylon), PC (polycarbonate), ABS, PC/ABS alloy and PPS (polyphenylene sulfide). Modifications include glass fibre reinforcement (GF10-GF50), mineral filling (TD20/TD30), impact modification, halogen-free flame retardance to UL94 V-0, UV and weather resistance, anti-static and conductive grades, and laser marking. Colours can be matched to your colour standard.
What is the minimum order quantity?
The MOQ is 500 kg for existing production grades and 1 tonne for a newly developed formulation. Small-batch sampling is supported, normally 5-25 kg for mould trials and performance verification.
How long do sampling and production take?
Samples of existing grades are ready in 3-7 days and new formulations in 7-15 days. After sample approval, standard production lead time is 10-20 days depending on grade and order quantity.
Do you supply TDS, COA and compliance documents?
Yes. Every grade can be supplied with a technical data sheet (TDS), a batch certificate of analysis (COA) and RoHS/REACH declarations. Third-party testing (UL94, RoHS / REACH) can be arranged on request for flame-retardant grades, and automotive grades supported with PPAP documentation under our IATF 16949 system.
Can your compounds replace the grade we run now?
Yes. We develop equivalent formulations benchmarked against the grade you run now. The material is first validated through small-batch mould trials, then phased in to reduce material cost while maintaining performance.
What are the shipping options and lead times?
We ship from Qingdao Port. Sea freight takes about 5-12 days to major ports in Vietnam and Thailand, and about 10-18 days to Indonesia and Malaysia. We support FOB, CIF and EXW terms and can ship through your nominated freight forwarder.
