Product Description
A specialty thermoplastic polyurethane elastomer designed for producing high-performance, high-durability suction cups.
Key Characteristics
1. Exceptional Elasticity & Resilience: Recovers quickly and fully after compression for optimal sealing and suction.
2. Extremely Low Compression Set: Excellent shape retention under prolonged pressure ensures long-term reliability.
3. Superior Abrasion & Tear Resistance: Durable edges and contact surfaces resist damage.Main Applications
Industrial heavy-load suction cups (e.g., for glass, sheet handling), robot end-of-arm-tooling (EOAT) grippers, high-frequency automation suction cups, outdoor or harsh environment suction devices, high-value equipment fixing cups.
Processing Methods
Injection Molding (Primary).
Environmental Certifications
ROHS, REACH. Halogen-free grades available.
Color
Transparent, translucent, black, or custom colors.
Storage Conditions
Strictly moisture-proof. Store sealed in a dry environment (<30°C).
Packaging
20/25 kg/bag.

Item
Parameter/Guideline
Drying
95-110°C / 4-5 hours (Mandatory and thorough to prevent bubbles and property loss)
Melt Temperature
190 - 210 °C
Mold Temperature
30 - 50 °C (High-gloss polished molds are recommended for a smooth, flat lip)
Injection Speed
Medium-low speed for complete filling and reduced internal stress.
Critical Precautions
1. Key Indicator: Compression Set is the most critical parameter determining cup lifespan and repeatable suction performance; it must be extremely low.
2. Bonding Application: If the cup needs bonding to a rigid base (metal, engineering plastic), evaluate adhesion methods or use mechanical assembly.Purge Suggestion
Purge thoroughly with ABS or HIPS at the lower end of the processing temperature range. Do NOT use PP or PE.
