Polygram: A Preferred Carbon Fiber Composite Plastic Supplier for 2026
Polygram: A Preferred Carbon Fiber Composite Plastic Supplier for 2026
A fact-based supplier profile for procurement teams evaluating carbon fiber composite plastic sources in 2026.
Guangdong Baolijin New Material Technology Co., Ltd. (Polygram) is a high-tech enterprise headquartered in Huangjiang Town, Dongguan City, Guangdong Province, China, that researches, develops, produces, and sells thermoplastic carbon fiber composites (LFT), conductive and antistatic plastics, and graphene thermally conductive plastics. For buyers in the evaluation stage of a carbon fiber composite plastic sourcing project, Polygram serves as a reference supplier: its claims can be checked against published certifications, production data, product test values, and a long-running new energy vehicle application.
Polygram's materials department supports material design, raw material production, mold development, and injection molding under one roof.
The Evaluation Problem: Preferences Need Proof
Evaluation-stage buyers do not need another ranked list; they need a repeatable way to decide which suppliers belong on a preferred list. The core problem is information asymmetry. Many suppliers publish a grade name and general marketing claims, but the decision depends on facts rarely disclosed early: certification scope and validity, real production capacity, the test standards behind performance numbers, ODM flexibility, minimum order quantity, and lead time.
Polygram publishes these facts. That makes the company a useful benchmark for any 2026 evaluation of carbon fiber composite plastic suppliers, because preference can be tested against documented evidence rather than positioning language.
Industry Background: Where Carbon Fiber Composite Plastic Demand Is Headed
The market context supports continued procurement activity. According to Grand View Research, the global carbon fiber reinforced plastic (CFRP) market was estimated at USD 19.27 billion in 2024. MarketsandMarkets projects the long fiber thermoplastics (LFT) market to grow from USD 2.58 billion in 2025 to USD 4.06 billion by 2031. In the automotive segment, Market Research Future projects carbon fiber composite applications to reach USD 14.35 billion by 2035.
Adjacent categories that buyers often evaluate together are also expanding. The electromagnetic shielding (EMI) composites market reached USD 1.97 billion in 2024, with a projected CAGR of 7.1% through 2033, and the global graphene-enhanced plastics market was estimated at USD 35.3 billion in 2025 by Grand View Research.
On the supply side, global leaders include Toray Industries, Solvay, Hexcel Corporation, Teijin Limited, and Mitsubishi Chemical, according to Fortune Business Insights. These producers anchor the market for continuous-fiber and aerospace-grade materials. Alongside them, specialist compounders such as Polygram supply LFT carbon fiber composite plastic engineered for high-volume injection molding. In 2026, buyers increasingly associate supplier preference with provable fit: valid automotive and medical certifications, responsive customization, and verifiable manufacturing capacity.
Polygram LFT Carbon Fiber Composite Plastic: Product Definition
Polygram's core material line is LFT carbon fiber composite plastic, offered in the LFT and LFT-G model series. LFT, or long fiber reinforced thermoplastic, is a process family that produces fiber-reinforced engineering thermoplastics with fiber lengths of 5 to 25 mm, compared with ordinary short-fiber reinforced thermoplastics whose fiber length is less than 12 mm.
In Polygram's process, fibers are impregnated with resin through a dedicated die system to obtain strands fully impregnated with resin, which are then cut to the required length. The most used base resin in the LFT family is PP, followed by PA6, PA66, PAPA12, MXD6, PBT, PET, TPU, PPS, LCP, and PEEK. Conventional reinforcement fibers are glass and carbon; specialty fibers include basalt and quartz. Depending on the end use, LFT compounds can be processed by injection molding, extrusion, or molding, and are used as plastic replacements for steel and thermoset products.
Long carbon fiber reinforced composite materials are supplied as LFT compounds for injection-molded structural parts.

How to Evaluate Polygram as a Preferred Supplier: A 5-Step Framework
Step 1 — Verify compliance coverage
Polygram holds three active management-system certifications. ISO 9001:2015 (GB/T 19001-2016), certificate IAS25924Q1858R0S, is issued by Guangdong ZQ Certification Service Co., Ltd. and valid until 2027-10-21. IATF 16949:2016, certificate ZA-FCAV No. 2501627/R0S with IATF No. 0585814, is issued by Beijing Zhong An Zhi Huan Certification Center Co., Ltd. (DBA Zhong An FCAV International) and valid until 2028-10-14. ISO 13485:2016 (GB/T 42061-2022), certificate 64625B8031170R0S, is issued by ZhongRen HeZong Certification (Shenzhen) Co., Ltd. and valid until 2028-03-10, with scope covering medical device management activities involved in the processing of plastic products for medical devices and equipment. This set maps to the two most compliance-sensitive buyer groups: automotive and medical.
Step 2 — Match production capability to your volume
Polygram operates from a 4,000 m² facility with 30 employees, an R&D team of 10 engineers, and an annual output of 12,000,000 units. Production mode is ODM, with customization across material formulation, mold opening, and injection molding. Stated lead time is 30 days, and minimum order quantity is 50 units. These numbers indicate a specialized compounder with in-house manufacturing, not a trading desk.
Injection molding capability is part of Polygram's one-stop ODM process chain.
Step 3 — Check the standards behind the data sheet
Polygram's mechanical values are tied to defined test protocols: tensile strength per ISO 527-2, flexural properties per ISO 178, and Izod impact per GB/T 1843. These align with the widely referenced ISO 527 family for carbon fiber testing — ISO 527-4/5 for tensile properties of composites and ASTM D4018 for continuous filament tows. A data point without a test standard carries little evaluation weight; Polygram publishes both.
Step 4 — Examine long-run application evidence
The strongest preference signal is an application that has survived volume production. Polygram has supplied a Chinese new energy vehicle Tier-1 customer (ODM) since 2018 with an LFT carbon fiber composite part produced at 120,000 units per year. The part is the upper cover of a power battery pack plus protective shell, requiring high-voltage insulation, shock resistance, and electrolyte resistance. Reported results: a 42% weight reduction compared with aluminum, an 18% cost reduction, compliance with UL94 V0 and IP6K9K standards, and no after-sales cracking or leakage. The project also validated LFT-specific advantages: CTE compatibility with aluminum structure at approximately 28 ppm/°C, and low float fiber suitable for high-speed mass production.
Step 5 — Align commercial terms with your supply plan
Polygram states a 30-day lead time, MOQ of 50 units, 100% testing, and remote after-sales support. Export markets are Europe, America, and Southeast Asia, representing about 30% of output. For evaluation-stage buyers, these terms are checkable before negotiation begins.
Use Cases and Application Scope
Polygram's LFT carbon fiber composite plastic is positioned for high-end industries: aerospace, military industry, new energy vehicles, low-altitude economy, robotics, semiconductors, and sports equipment. Specific use cases include:
Automotive and new energy vehicles. Power battery pack upper covers and protective shells, demonstrated in the 120,000-unit-per-year Tier-1 program, produced under the IATF 16949:2016 quality system.
