Select premium grades designed to withstand wear, friction, impact, and chemical degradation in extreme operating environments.
Polyoxymethylene (POM), commonly recognized under trade names such as Acetal or Delrin, represents a class of high-crystallinity thermoplastic polymers engineered specifically to serve as high-load, high-rigidity structural replacements for conventional metals. In its natural, unmodified state, POM exhibits a clean, semi-opaque White appearance. Because of its outstanding mechanical stability, negligible moisture absorption, and low coefficient of friction, the **White POM Sheet** has established itself as an indispensable raw material in modern precision manufacturing.
As a leading **China White POM Sheet Manufacturer**, Tianjin Beyond Technology Development Co., Ltd. integrates advanced extrusion technologies and precision annealing processes to deliver sheets that remain perfectly flat and stress-relieved. When selecting Acetal sheets for industrial production, engineers must evaluate whether a Copolymer (POM-C) or Homopolymer (POM-H) best fits the design requirement. Copolymer variants provide superior resistance to hot water, strong alkalis, and thermal oxidative degradation, whereas Homopolymers exhibit higher tensile strength, hardness, and creep resistance.
"In precision CNC machining, material stress relief is the differentiator between a component that holds micron-level tolerances and one that warps after tool extraction. Tianjin Beyond's proprietary double-annealing cycle eliminates residual extrusion stresses, guaranteeing unparalleled dimensional stability."
Tianjin Beyond Technology Development Co., Ltd. is a comprehensive manufacturing enterprise specializing in engineering plastic materials and precision CNC machining. Since 2015, the company has gained more than ten years of practical experience in engineering plastics manufacturing and precision CNC machining, building strong and reliable capabilities in material processing, precision control, and industrial production.
Our manufacturing base spans approximately 50,000 square meters and integrates compression molding and extrusion workshops, a state-of-the-art precision CNC machining center, and a dedicated R&D facility. Outfitted with advanced international equipment—including high-throughput compression molding and extrusion lines, gantry CNC lathes, gantry CNC milling machines, and large-scale CNC engraving systems—this integrated setup allows us to ensure consistent quality, maintain efficient production, and deliver high-precision, large-volume, and customized products that meet the highest industrial standards.
We focus on the manufacturing of UHMWPE, HDPE, PP, and PVC sheets and rods, as well as a wide range of custom non-standard engineering plastic components and precision metal CNC machined parts, providing flexible and application-oriented solutions for diverse industrial requirements.
Innovating the boundaries of Acetal polymer structures to fulfill the challenges of high-frequency, high-wear automation systems.
From high-speed European packaging plants to North American precision defense electronics, POM delivers optimal component performance.
White POM is FDA compliant, non-toxic, and resistant to aggressive chemical CIP (Clean-In-Place) washdowns. It is widely machined into filler gears, star wheels, sorting manifolds, and conveyor components that come into direct contact with dairy, meat, and dry foodstuffs.
Used extensively for structural components in window regulators, seat belt retractor gears, fuel system senders, and wiper linkages. Acetal's low creep under stress ensures long-term operational integrity over a broad temperature range (-40°C to 90°C).
With a high dielectric strength and resistance to electrical tracking, White POM is utilized for terminal strips, structural insulators, electronic housing components, and high-frequency connectors where moisture absorption would degrade electrical performance.
How Tianjin Beyond guarantees steady capacity, premium raw materials, and seamless shipping in a volatile global economy.
In the global engineering plastic market, supply stability is paramount. Tianjin Beyond Technology Development Co., Ltd. leverages its strategic location in Tianjin (home to the major northern China maritime logistics hub) to maintain a steady flow of high-grade raw materials and prompt international deliveries. We maintain a raw material purchasing network that includes premium grade supply partnerships with global leaders like TICONA (Celanese), LG Chem, and Sinopec. This ensures that every batch of White POM Sheet processed at our facility conforms to predictable physical properties.
Our facility integrates advanced gantry CNC milling, turning, and engraving machinery that operates alongside our extrusion lines. By offering both primary sheet production and secondary CNC machining under a single roof, we cut down lead times by up to 35% compared to outsourcing loops. Our engineering team converts CAD blueprints directly into precision-finished parts like custom POM gear racks, bushings, and guides.
By testing and qualifying every incoming polymer batch, we guarantee density profiles (1.41-1.42 g/cm³) and moisture absorption limits (≤0.2%) conform strictly to datasheets before extrusion begins.
Detailing our diverse corporate partnerships, quality sourcing networks, and specialized biotech raw materials divisions.
Premium products come from high-quality raw materials. Ya’an Times Biotech Co., Ltd. is located in Ya’an, Sichuan, where the altitude varies greatly from 525 meters to 7555 meters. The diverse landforms and ambient temperatures provide a proper growth environment for a large number of plants which are main sources of high-quality pure natural raw materials of our products.
The raw material oils used in the production of essential oils, food and cosmetics are the second largest category of our products, such as camellia oil, eucalyptus oil, turmeric oil and pepper oil, etc. Times Biotech selects high-quality raw materials with high standards, strictly controls and supervises the whole production and extraction process, and adopts strict inspection standards to guarantee our oils to be the premium raw material oils which can be your best choice for your products.
We have an independent laboratory and R&D team, and we have experienced material engineers, technical engineers, production engineers and engineering plastics experts. At present, our company is a high-quality raw material purchaser of TICONA, LG, Sinopec and other companies, and has cooperated with many universities and colleges. Beyond has many cooperation with plastic institutions on engineering plastics research and development.
With decades of experience in plastics production and research & development, Tianjin Beyond Technology Developing Co., Ltd. has become a powerful engineering plastics material processing manufacturer in China, and is getting more and more regular buyers all over the world.
Our facilities and operations adhere to global benchmarks including ISO9001, SGS, and BV. From raw materials entering the factory, production and processing, to finished products, we carry out strict quality inspection and monitoring in accordance with the ISO9001 quality system. We have a complete quality inspection system, raw materials, sample inspection, random test during production, COA of end products, strictly control the product quality, so that unqualified products could not go out of the factory.
