Features & Benefits

• Balanced rigidity and low-temperature toughness, maintaining notable notched impact strength even at -20℃ so that finished parts are less prone to low-temperature brittleness.

• Moderate melt flow rate with stable fluidity, making it suitable for molding complex structures and thin-walled injection parts with a wide processing window.

• Excellent environmental stress crack resistance, withstanding everyday oils, weak acids, weak bases, and other chemical erosion for long-term durability without cracking.

• Stable molding shrinkage with a parallel shrinkage rate of 1.4%, helping ensure dimensional consistency across components.

• Good ductility with high elongation at break, giving parts strong flexural endurance suitable for repeatedly assembled or disassembled plastic fittings.

• Consistent original-factory polymerization process with minimal batch-to-batch property fluctuations, ideal for large-scale continuous mass production.

Applications

1. Automotive Industry: Automotive interior and exterior plastic parts, door panel accessories, storage boxes, air conditioning housings, and peripheral lamp brackets capable of withstanding alternating high and low-temperature working conditions.

2. Consumer Goods: Storage boxes, turnover crates, plastic toolboxes, buckets, household storage containers, and structural components for sports equipment.

3. Home Appliances: Internal support structures, housing linings, and functional bases for washing machines, air conditioners, and small appliances.

4. Packaging & Logistics: Plastic pallet accessories, industrial turnover containers, and detachable plastic boxes.

5. General Industrial Parts: General machinery plastic housings, fastener bases, and small pump/valve shells.

Frequently Asked Questions (FAQs)

Q1: Is pre-drying required before processing Globalene® 7633 PP?

A: Under normal conditions, this grade has extremely low water absorption and unwetted raw material does not require drying. If the material has been stored for a long time or exposed to a humid environment, pre-drying at 80~90℃ for 2~3 hours is recommended to prevent surface defects such as bubbles and silver streaks.

Q2: What are the core differences between Globalene® 7633 PP and homopolymer PP?

A: Grade 7633 is a block copolymer polypropylene. Compared to homopolymer PP, it significantly improves low-temperature impact performance, making it less susceptible to brittle fracture in cold environments. Its rigidity is slightly lower than that of homopolymer PP, making it better suited for structural parts requiring low-temperature performance, whereas homopolymer PP offers higher rigidity and better high-temperature resistance but poorer low-temperature toughness.

Q3: Does this grade comply with food-contact and RoHS environmental requirements?

A: LCY Globalene® 7633 base resin meets RoHS hazardous substance control requirements. For food-contact applications, please request the original factory compliance report from the supplier and complete end-product verification in accordance with target regional regulations (such as FDA or GB 4806).

Q4: Is this raw material suited for extrusion molding or injection molding?

A: Globalene® 7633 is primarily positioned as an injection-grade copolymer PP, optimized specifically for injection molding processes. It is not recommended for high-speed film extrusion, fiber spinning, or other extrusion applications; for extrusion purposes, selecting LCY’s dedicated extrusion-grade materials is recommended.
