M1207
M1207 is a double-coated rubber-based adhesive tape constructed with an aggressive permanent adhesive on both faces: 1.6 mils on the exposed side and 1.4 mils on the liner side, supported by a 0.5 mil PET film carrier. Peel adhesion reaches 115 ozf/in on stainless steel (liner side) and 100 ozf/in on ABS, with Polyken probe tack values of 1,875 g (liner side) and 1,450 g (exposed side), and shear hold exceeding 10,000 minutes on both faces. The tape passes FMVSS-302, UL723 25/50 smoke/spread, and 21 CFR 175.105 indirect food contact requirements.

M1207 is a double-coated rubber-based adhesive tape engineered with an aggressive permanent adhesive system on both the liner and air sides. The construction pairs 1.6 mils of rubber adhesive on the exposed face with 1.4 mils on the liner face, separated by a 0.5 mil PET carrier that provides dimensional support and enhanced die-cutting performance. The 76# poly-coated kraft liner supports smooth converting operations.
The asymmetric adhesive thicknesses are intentional: the liner side delivers slightly higher peel and tack performance than the exposed side, consistent with the typical PSA design pattern where the liner-protected adhesive is tuned for the most demanding bonding interface.
Performance is strong across polar and semi-polar substrates: peel adhesion on stainless steel reaches 95 ozf/in (exposed) and 115 ozf/in (liner) at 20-minute dwell per PSTC-101/ASTM D3330, with ABS values of 75 ozf/in (exposed) and 100 ozf/in (liner). Polyken probe tack reaches 1,450 g (exposed) and 1,875 g (liner) — high values indicating aggressive initial grab. Shear adhesion exceeds 10,000 minutes under both 500 g and 1,000 g loads on both faces.
Elevated temperature performance is measured via ASTM D4498 (modified) at 180°F on the exposed side and 185°F on the liner side. M1207 carries three meaningful compliance credentials: FMVSS-302 automotive flammability, UL723 25/50 smoke/spread flame rating, and 21 CFR 175.105 indirect food contact, plus the TDS states it meets skin contact application requirements. Application temperature is 50°F to 100°F.
Compliant with FMVSS-302, UL723 (25/50 Smoke/Spread), and 21 CFR 175.105 (Indirect Food Contact).
What differentiates M1207 from other double-coated rubber tapes?
M1207 carries three meaningful compliance credentials that extend its applicability beyond general bonding: FMVSS-302 automotive flammability, UL723 25/50 smoke/spread flame rating, and 21 CFR 175.105 indirect food contact. The TDS also states M1207 meets skin contact application requirements. Few rubber-based tapes carry this combination — making M1207 a practical single-SKU selection across automotive interior, transit, food-equipment, and medical converting applications.
Why is peel adhesion important when selecting this tape?
Peel adhesion reflects real-world bond strength under separation loading. The M1207 TDS reports substrate-specific values on both stainless steel (95 / 115 ozf/in) and ABS (75 / 100 ozf/in) with the liner side consistently higher than the exposed side — a deliberate asymmetric design. The very high Polyken probe tack values (1,450 g exposed / 1,875 g liner) confirm aggressive initial grab, supporting rapid assembly-line handling.
What is the temperature range for M1207?
M1207 has an application temperature range of 50°F to 100°F, with elevated temperature test values of 180°F (exposed side) and 185°F (liner side) per ASTM D4498 modified.
Is M1207 suitable for flame-rated, food-contact, or automotive interior applications?
Yes. The TDS confirms compliance with FMVSS-302 (automotive flammability), UL723 25/50 smoke/spread (flame rating), and 21 CFR 175.105 (indirect food contact), and states the adhesive meets skin contact application requirements. This combination makes M1207 suitable for all four categories of regulated application.
How should M1207 be specified?
Specify grade (M1207), adhesive thickness per side (1.6 mils exposed / 1.4 mils liner), carrier (0.5 mil PET), liner (76# poly-coated kraft), compliance requirements (FMVSS-302 / UL723 / 21 CFR 175.105 as applicable), dimensional tolerances, and finished format
