PI Material High Temperature Resistant 300 Tape’s molecular structure 赋予 it unparalleled resistance to aggressive chemicals:
Sulfuric Acid Test: In 98% sulfuric acid at 200°C, it loses <1% weight after 500 hours. Self - Adhesive Back Blocking Spray Paint Tape dissolves within 24 hours under the same conditions.
Solvent Immunity: Unaffected by acetone, benzene, and hydrochloric acid, maintaining adhesion and integrity in cleaning and production processes.
Chemical Barrier Coatings: Nano - composite layers prevent acid penetration, unlike competitors that absorb chemicals and swell.
Application Example: In a petrochemical plant’s distillation tower, PI Tape seals flange joints, reducing downtime from monthly maintenance to annual inspections.
Chemical processes often involve rapid temperature fluctuations:
Wide Temperature Range: Operates continuously at 260°C and survives 300°C spikes, critical for reactor heating cycles.
Thermal Cycling: Withstands 1,500 cycles of - 196°C to 300°C (vs. Self - Adhesive Tape’s 200 cycles), preventing embrittlement and delamination.
Low Thermal Expansion: 0.5% dimensional change at 300°C vs. 20% for PET - based tapes, ensuring tight seals in piping systems.
Case Study: A pharmaceutical plant using PI Tape on reactor gaskets saw a 90% reduction in leaks during steam sterilization cycles.
PI Tape’s physical properties enable long - term performance:
High Tensile Strength: 200 MPa vs. 80 MPa for Self - Adhesive Back Blocking Spray Paint Tape, resisting tearing under pressure.
Adhesion Retention: 4.5 N/cm peel strength after 1,000h in 98% sulfuric acid, compared to 0.3 N/cm for competing tapes.
Flex Fatigue Resistance: 200,000 bends at - 50°C without cracking, ideal for flexible hoses and moving parts.
Industrial Use: PI Tape reinforces fiberglass pipes in chemical transport, extending service life from 2 to 7 years.
PI Material High Temperature Resistant 300 Tape meets stringent industry standards:
Flame Retardancy: UL 94 V - 0 rating, self - extinguishing within 10 seconds.
Low Outgassing: TML <0.3% (ASTM E595), preventing sensor contamination in cleanroom chemical processing.
FDA Compliance: Non - toxic formulation for food and pharmaceutical applications.
Regulatory Edge: A biotech facility switched to PI Tape for fermenter seals, avoiding product recalls due to chemical migration.
While PI Tape has a higher upfront cost, its longevity reduces lifecycle expenses:
ROI Analysis: 220% savings over 5 years in SMT assembly (per previous LVMEIKAPTON case studies).
Maintenance Reduction: 80% fewer replacements than Self - Adhesive Back Blocking Spray Paint Tape in chemical storage tanks.
Energy Savings: Insulative properties reduce heat loss in pipelines, cutting energy costs by 15%.
Traditional tapes like Self - Adhesive Back Blocking Spray Paint Tape and Strong Adhesion and Blocking High Temperature Tape lack the chemical resistance and thermal stability required for chemical plants:
Chemical Degradation: PET and acrylic tapes hydrolyze in acidic environments.
Thermal Breakdown: Adhesives carbonize at 200°C, causing leaks and system failures.
Mechanical Weakness: Brittleness at low temperatures leads to micro - cracks and fluid ingress.
LVMEIKAPTON is developing next - generation PI Tape for chemical plants:
Graphene Reinforcement: 50% higher tensile strength for high - pressure applications.
pH - Responsive Adhesives: Maintain bond in dynamic chemical environments.
3D - Printed Tape Solutions: Customizable seals for complex equipment geometries.
PI Material High Temperature Resistant 300 Tape’s combination of chemical inertness, thermal resilience, and mechanical strength makes it indispensable for chemical plants. Its ability to withstand 98% sulfuric acid and extreme temperatures far exceeds competitors like Self - Adhesive Back Blocking Spray Paint Tape. As industries adopt stricter safety and efficiency standards, PI Tape will continue to set the benchmark for reliability in harsh chemical environments. Strong Adhesion and Blocking High Temperature Tape’s complementary role in less corrosive settings further solidifies the importance of polyimide - based solutions across industrial sectors.
