Business Operations and Segments

Deyi New Material’s activities can be grouped into four closely connected operating areas:

The company’s operating model combines materials development with production and technical support. This structure is relevant in specialty plastics because customers often require more than a resin: they may need a compound with defined filler content, reinforcement, friction behavior, electrical characteristics, color, shrinkage, or processing stability.

Products and Technologies

High-performance polymer systems

The company works with polymer families selected for demanding thermal, mechanical, chemical, and electrical requirements:

• PEEK: Used where high temperature resistance, chemical resistance, fatigue performance, and low friction are required.
• PEI: An amorphous engineering polymer associated with high heat resistance, dimensional stability, and electrical performance.
• PI: Used in applications requiring exceptional thermal stability and resistance to harsh operating environments.
• PAI: Valued for high strength, wear resistance, and performance under elevated temperatures.
• PPS: A semi-crystalline polymer with strong chemical resistance, dimensional stability, and useful flame-resistance characteristics.
• PPSU and PSU: Sulfone-based polymers used where heat resistance, toughness, hydrolytic stability, or chemical resistance is important.
• LCP: A high-flow specialty polymer suitable for thin-wall precision molding and selected electrical or electronic applications.

Compounding and modification

Deyi New Material’s technical work centers on compound modification, in which a base polymer is combined with reinforcing fibers, mineral fillers, lubricants, conductive additives, stabilizers, or other functional components. Depending on the formulation, modification may be used to improve:

• Tensile strength and stiffness
• Wear and friction behavior
• Dimensional stability
• Thermal endurance
• Electrical insulation or conductivity
• Flame resistance
• Chemical resistance
• Processing behavior and surface quality

The resulting materials are supplied in pelletized forms suitable for injection molding and other thermoplastic-processing operations. The company also supplies rods and sheets, which can be machined into prototype parts, sealing components, wear elements, insulating structures, and other technical products.

Processing relevance

Specialty thermoplastics generally require stricter processing control than conventional plastics. Important factors include drying, melt temperature, mold temperature, residence time, shear history, shrinkage, and post-molding conditioning. Semi-crystalline polymers such as PEEK and PPS require controlled crystallization to achieve predictable dimensional and mechanical properties, while amorphous materials such as PEI and PSU require careful management of residual stress and thermal history.

Deyi’s provision of customized formulations and testing services positions it within the application-engineering segment of the plastics industry, where compound design and processing guidance are closely connected.

Applications and End Markets

The company’s materials are suitable for industries that require performance beyond that normally provided by commodity polymers. Relevant application areas include:

• Electrical and electronic components
• Precision mechanical parts
• Automotive and transportation systems
• Industrial equipment
• Chemical-processing equipment
• Pumps, valves, seals, and bearing components
• Medical and laboratory equipment
• Aerospace-related and other high-temperature applications
• Insulation and high-performance structural components

The exact suitability of a material depends on polymer grade, reinforcement package, processing method, regulatory requirements, and operating conditions. For example, an unfilled PEEK grade may be selected for chemical resistance and toughness, whereas a carbon-fiber- or glass-fiber-reinforced compound may be preferred for stiffness and dimensional control. Wear-modified grades may be used for sliding components, while conductive or antistatic formulations address electrical-performance requirements.

Research and Development

Research and development is central to Deyi New Material’s business model. The company describes its activities as including compound-modification research, material testing, customized development, and production.

Its R&D work is likely to involve several technical stages:

1. Selection of a polymer matrix according to temperature, chemical, mechanical, electrical, or tribological requirements.
2. Selection of reinforcement or functional additives.
3. Laboratory compounding and characterization.
4. Processing trials using the customer’s intended molding or machining method.
5. Adjustment of formulation and processing parameters.
6. Validation of consistency and application performance.

In specialty plastics, R&D is often application-specific rather than limited to the creation of entirely new polymers. Improvements may involve optimizing filler dispersion, reducing warpage, controlling friction and wear, improving surface finish, or balancing stiffness with toughness.

Sustainability and Environmental Considerations

High-performance engineering plastics can contribute to resource efficiency when they replace heavier metal components, extend component service life, reduce lubrication requirements, or enable smaller and lighter assemblies. Their long service life can also reduce the frequency of replacement in demanding industrial applications.

At the same time, specialty polymers present environmental challenges. Many require high processing temperatures, and some are difficult to recycle because of high-performance additives, fiber reinforcement, contamination, or the absence of established collection streams. Thermoset-like performance requirements and multi-material assemblies can further complicate recovery.

For Deyi New Material, the most relevant sustainability considerations include:

• Improving material durability and service life
• Developing formulations that reduce component mass
• Supporting precise processing to minimize scrap
• Evaluating the recyclability of production waste
• Managing energy consumption during compounding and molding
