What are Polycarbonate Granules<\/span><\/h1>\n

 <\/p>\n

PC 1803 is a high-viscosity transparent polycarbonate material designed for automotive lighting and precision injection molding. It is in the form of granules (polycarbonate granule) and is suitable for the production of thick-walled lampshades, complex light-guiding structures, and mold components with extremely high requirements for heat resistance and dimensional accuracy. It has the following features:<\/span><\/p>\n

\u00a0 \u30fb<\/strong>The Vicat softening point is as high as 184\u00b0C, which can withstand long-term LED heat source radiation;<\/span><\/p>\n

\u00a0 \u30fb<\/strong>Excellent dimensional stability and anti-UV aging ability;<\/span><\/p>\n

\u00a0 \u30fb<\/strong>Supports high-precision injection molding and in-mold assembly to meet complex design requirements.<\/span><\/p>\n

01\uff5cIndustry background: Material upgrade turning point in the evolution of automotive lighting<\/span><\/h2>\n

 <\/p>\n

Automotive lamps, especially LED lighting systems, are undergoing a transformation from \"appearance aesthetics\" to \"structural composite functions\". Lampshades and light guide components are no longer simple covers, but must take into account:<\/span><\/p>\n

\u00a0 \u30fbHigh optical performance<\/strong> (light transmittance, refraction control)<\/span><\/p>\n

\u00a0 \u30fbStructural strength and heat resistance<\/strong> (LED chip heat load)<\/span><\/p>\n

\u00a0 \u30fbSurface stability<\/strong> (UV resistance, scratch resistance, long-term transparency)<\/span><\/p>\n

Under such multiple requirements, traditional general-purpose PC materials (such as low-viscosity grades) are difficult to cope with high temperature, thick wall and precision assembly scenarios. This also promotes high-performance polycarbonate granules such as PC 1803 to become the first choice for engineers in the design and material selection stage.<\/span><\/p>\n

\ud83d\udd38 Thermal Performance: High Temperature Resistance and No Deformation<\/strong><\/span><\/p>\n

Vicat Softening Point: 184\u00b0C<\/span><\/strong><\/p>\n

Adapt to continuous heating under LED light sources without the need for additional reinforcements or air duct structures.<\/span><\/p>\n

Long-term thermal aging stability<\/span><\/strong><\/p>\n

By adding a thermal stabilization system, PC 1803 still maintains good optical properties and mechanical strength after aging continuously at 120\u00b0C for 1,000 hours.<\/span><\/p>\n

 <\/p>\n

\ud83d\udd38 Dimensional control: the core indicator of module assembly<\/span><\/strong><\/p>\n

Linear shrinkage: about 0.85%<\/span><\/strong><\/p>\n

Compared with standard general PC grades (shrinkage of about 0.9-1.2%), PC 1803 has better control capabilities and is suitable for precision structures such as snap-on positioning and sealing ring matching.<\/span><\/p>\n

Low hygroscopicity design<\/span><\/strong><\/p>\n

Avoids dimensional changes or warping problems caused by water absorption after injection molding.<\/span><\/p>\n
