A702 is a single-coated self-wound acrylic film tape engineered for high-temperature service. The construction pairs a 2.00 mil polyester (PET) film carrier with 1.50 mils of permanent acrylic pressure sensitive adhesive, producing a 3.50 mil total stack that can be unwound directly without a release liner (self-wound).
The PET carrier provides high tensile strength (50 lb/in per PSTC 131), dimensional stability, and dielectric performance characteristic of polyester film tapes, while the acrylic adhesive system maintains bond integrity at elevated temperatures.
Peel adhesion is 54 oz/in per PSTC-101, with 30 oz/in tack (ASTM D2979) providing rapid initial grab. Shear hold under a 2.2 psi load is 168 hours (7 days) per PSTC 107, confirming strong resistance to static load creep.
The maximum service temperature of 300°F positions A702 among the higher-temperature acrylic tapes in the product family — appropriate for high-heat environments including underhood automotive, industrial electronics, and thermal processing applications. Minimum service temperature is −40°F, supporting broad thermal cycling capability.
What differentiates A702 from other acrylic PET film tapes?
A702 is positioned specifically for superior high-temperature performance, with a 300°F maximum service temperature that exceeds most general-purpose acrylic film tapes. The 2.00 mil PET carrier provides strong tensile support (50 lb/in) and dimensional stability, while the acrylic adhesive maintains bond integrity at elevated temperatures. The self-wound format (no release liner) simplifies handling and dispensing compared to lined constructions.
Why is peel adhesion important when selecting this tape?
Peel adhesion measures the tape's resistance to separation from a substrate under controlled peel conditions, reflecting real-world bond durability. For A702, the 54 oz/in peel value combined with 168-hour shear hold at 2.2 psi confirms the adhesive maintains strong interfacial bonding and resists creep over extended periods — important characteristics for high-temperature applications where bond degradation is a common failure mode.
What is the service temperature range for A702?
A702 has a service temperature range of −40°F to 300°F.
Is A702 suitable for high-temperature industrial or automotive applications?
Yes. The TDS explicitly positions A702 for "superior performance in high temperature applications" and cites the PET film carrier and acrylic adhesive as contributing to high-temperature integrity. The 300°F maximum service temperature supports underhood automotive and industrial processing use. No specific regulatory compliance standards are listed on the TDS for this material.
How should A702 be specified?
Specify grade (A702), adhesive thickness (1.50 mils), carrier thickness (2.00 mils PET), total thickness (3.50 mils), compliance requirements, dimensional tolerances, and finished format.
