What are PC Pellets

With the continuous upgrading of material performance requirements for electronic appliances, smart devices and outdoor equipment, especially in terms of low-temperature impact resistance, high rigidity and environmental friendliness, traditional halogen-containing flame-retardant PC pellets are gradually unable to meet the ecological standards and user experience of the new era. The siloxane copolymer flame retardant technology equipped on PC EXL9330 provides a high-performance alternative to such challenges. It is a highly innovative non-chlorine and non-brominated flame retardant polycarbonate pellets that combines high impact resistance, high strength, high toughness and excellent UV weather resistance.

01 | Technical Highlights Revealed: Unprecedented Performance Balance

Non-chlorine, non-bromine, green flame retardant

EXL9330 adopts halogen-free flame retardant technology and meets international environmental protection certifications (such as RoHS and REACH). It is flexible in HB, V‑1, V‑0, 5VB, 5VA multi-level flame retardant standards, suitable for industrial applications with different requirements for flame propagation control.

High impact · High strength · high rigidity

Siloxane modification enables the material to maintain excellent impact resistance in low-temperature environments while ensuring a balance between rigidity and strength, making it suitable for high-strength structural components and casings.

Outstanding weather resistance and UV resistance

It contains UV protectors and is suitable for long-term outdoor exposure environments. The precision surface is not prone to yellowing, powdering or cracking, meeting the expected service life of more than 5 years.

ประสิทธิภาพการกระแทกที่อุณหภูมิต่ำที่ยอดเยี่ยม

It still has high elasticity and impact toughness in low-temperature environments, and is suitable for outdoor and high-cold region equipment components, such as communication equipment, outdoor lighting and charging pile shells.

High-efficiency processing attribute

The material is in granular form and suitable for injection molding. Lubricants and mold release agents have been added, demonstrating a 70% smoother demolding quality, reducing molding defects and mold wear.

02 | Wide application fields: The first choice that combines intelligence and durability

03 | Processing adaptability: Optimized injection molding process facilitates efficient batch molding

EXL9330 is specially optimized for injection molding, featuring excellent fluidity and demolding efficiency. It is suitable for high-speed injection molding of medium and large-sized structural components, high-detail shells, and multi-cavity molds.

  -It is suitable for thick-walled or complex-structured products, with strong flow balance and excellent warpage control.

  ・Adding lubricating and demolding AIDS significantly reduces the probability of mold adhesion and surface defects.

  -It has strong thermal stability, avoiding decomposition and discoloration problems during high-temperature injection molding.

  -It supports complex processes such as two-color injection molding and insertion molding, and is suitable for the integration requirements of multiple structural components in smart devices.

Suggested processing parameter range

  ・Feeding cylinder temperature: 260-300°C

  ・Mold temperature: 80-110°C

  ・Injection speed: Medium to high speed

  ・Drying conditions: 100°C for 4 hours

04 | Market Trends and Innovative Value

With the continuous growth of the global green manufacturing and high-end electronic products market, material supply needs to have four core elements: performance, environmental safety, cost and supply stability. The EXL9330 is targeted at a high-demand niche market that not only needs to meet strict fire protection standards but also must not contain chlorine or bromine substances. To meet such demands, materials need to achieve a leapfrog upgrade:

  -Material trend: Gradually evolving from "heavy materials with excessive performance" to "balanced performance, lightweight, and environmentally friendly".

  -Technical trends: Siloxane copolymerization → Heterogeneous flame retardant system → Halogen-free and odorless → One-time molding

  -Market trends: Intelligent manufacturing, green printing, sustainable design, standard compatibility, etc. are terminal-oriented.

EXL9330 emerged precisely under the above trends and represents a new benchmark for the next generation of high-performance polycarbonate.
