What is PC Plastic Material

In the field of high-precision injection molding, material demoulding performance, dimensional stability and environmental compliance are becoming important criteria for parts manufacturers to measure pc plastic material. PC 121R-21051 is an engineering-grade polycarbonate material that was born in response to this trend. It is not just "another PC", but a non-halogenated demoulding PC plastic material optimized for complex structural parts. It has multiple advantages such as self-demolding, thermal stability, strong electrical performance, and complete certification.

01 | Why choose PC 121R-21051?

✔ Self-contained demoulding agent, optimized for complex injection molding structures

Compared with traditional PC plastic materials, the biggest highlight of PC 121R-21051 is its "self-contained demoulding properties", which can achieve smooth demoulding even in complex injection molded parts (such as micro buckles, guide rails, gear components, etc.), reduce mold wear, reduce defective rates, and shorten production cycles.

✔ Non-halogen formula, meeting global environmental regulations

PC plastic material adopts a completely non-halogenated environmentally friendly formula, without the need to add flame retardants or release agents, and is easier to meet international standards such as EU RoHS, REACH, California 65, UL94 HB, and is particularly suitable for export electronics, home appliances, electrical components and other applications.

✔ Balance in thermal, electrical and impact performance

Although it is positioned for demolding optimization, PC 121R-21051 plastic material still maintains excellent performance in key indicators such as thermal deformation, electrical insulation, and low-temperature impact toughness, providing stable and reliable long-term performance guarantees for parts, and maintaining structural strength and safety even in complex environments.

02 | Application scenario: When traditional PC plastic material encounters extreme structural challenges

When facing the following types of products, the advantages of PC 121R-21051 are particularly prominent:

  ・Complex structure: electronic connectors, snap-on housings, small component housings

  ・Mold precision: mirror-finished high-gloss injection molding parts, precision positioning components, hidden buttons

  ・High production line beats: home appliance automation injection molding, 3C small parts continuous production

  ・High certification requirements: electrical and consumer products exported to North America and the EU market

For these working conditions, traditional PCs are often difficult to demold, have too many burrs, and are unstable in thermal shock, while PC 121R-21051 provides full support in terms of "precision + fast + stable + compliance".

03 | Multiple certifications and environmental compliance, helping global applications

PC 121R-21051 meets multiple international standard tests:

  ・UL 94 fire rating HB

  ・IEC, ISO and other mechanical, electrical, thermal specifications

  ・Limiting oxygen index reaches 25%, with certain flame retardant properties

For customers who need to pass the global certification system (such as electronic and electrical products exported to Europe and the United States), this PC plastic material provides a good compliance basis.

04 | Market trends and international procurement suggestions

The current global plastic industry is moving towards high added value, functional complexity and sustainable development. Small electronic modules, sensor housings, lightweight home appliance parts, smart wear connectors, etc. have put forward higher requirements for materials such as light weight, high strength, environmental protection, and easy demolding.

PC 121R-21051 just follows this trend and fills the gap in the "non-halogenated + easy demolding" formula in mid-to-high-end injection molding PC plastic materials.
