1. Extreme Temperature Resistance
ThePI Material High Temperature Resistant 300 Tapeis engineered to withstand temperatures up to 300°C continuously. Polyimide (PI), a thermally stable polymer, forms the backbone of this tape. Unlike conventional materials like silicone or acrylic, PI does not degrade, melt, or lose adhesion under extreme heat.
Property | PI Tape | Self-Adhesive Spray Paint Tape |
Max Operating Temperature | 300°C | 150°C |
Thermal Shrinkage (200°C) | <1% | >5% |
Flame Resistance | UL94 V-0 | UL94 HB |
This makes theStrong Adhesion and Blocking High Temperature Tapeideal for insulating pipelines, reactors, and exhaust systems in chemical plants.
2. Superior Chemical Resistance
Chemical plants frequently use corrosive substances like sulfuric acid, hydrochloric acid, and solvents. ThePI Material High Temperature Resistant 300 Taperesists degradation even when exposed to 98% sulfuric acid for 500 hours (<1% weight loss). In contrast,Self-Adhesive Back Blocking Spray Paint Tapedissolves due to its acrylic-based adhesive and PVC backing.
Key Chemical Resistance Comparison
|Chemical|PI Tape Performance|Spray Paint Tape Performance|
|------------------------|--------------------------|-----------------------------------|
| 98% H₂SO₄ (500h) | <1% weight loss | Dissolved |
| 30% NaOH (300h) | No corrosion | Adhesive failure |
| Acetone (200h) | No swelling | Delaminated |
This resistance ensures long-term protection for equipment, reducing maintenance costs.
3. Strong Adhesion and Sealing Performance
TheStrong Adhesion and Blocking High Temperature Tapecombines polyimide film with a silicone adhesive, creating a bond that remains intact under heat and chemical exposure. Its adhesion strength (≥8 N/cm) outperforms rubber-based or acrylic tapes (≤3 N/cm).
Applications include:
· Sealing flange joints to prevent leaks.
· Insulating electrical components in corrosive zones.
· Blocking UV and ozone degradation in outdoor setups.
4. Long-Term Durability in Harsh Environments
ThePI Material High Temperature Resistant 300 Taperesists aging caused by moisture, UV radiation, and mechanical stress. Accelerated aging tests show less than 10% loss in tensile strength after 1,000 hours, whereasSelf-Adhesive Back Blocking Spray Paint Tapedegrades by 50% in the same period.
5. Case Study: PI Tape in Sulfuric Acid Storage
A chemical plant replaced traditional tapes with thePI Material High Temperature Resistant 300 Tapeto seal storage tanks containing 98% sulfuric acid. Over six months, the tape showed no visible wear, while previous tapes required weekly replacements. This reduced downtime by 80%.
Conclusion
ThePI Material High Temperature Resistant 300 Tapeoutperforms alternatives likeSelf-Adhesive Back Blocking Spray Paint Tapedue to its unmatched heat resistance, chemical stability, and adhesion strength. For chemical plants prioritizing safety and efficiency, this tape is a critical investment.
