Silicone Pressure-Sensitive Adhesive (PSA)

Silicone PSAs are formulated by blending MQ or MDT silicone resins with high-molecular-weight PDMS gum, delivering aggressive tack and high peel strength on low-surface-energy and high-temperature substrates where acrylic PSAs fail. Medical tape, electronics masking, and aerospace thermal protection are their primary markets.

Specifications

Peel Strength (180°)8–25 N/25mm
Loop Tack6–20 N/25mm
Shear (1 kg/25×25 mm)>10,000 min
Service Temperature-60 °C to +200 °C
ComplianceFDA 21 CFR 175.300, USP Class VI (selected grades)

Applications

  • Medical tape, wound care dressings, and transdermal drug patches
  • High-temperature electronics masking tape (wave soldering, powder coating)
  • Low-surface-energy substrate bonding (PTFE, silicone rubber, polyolefin)
  • Aerospace thermal blanket and heat-shield attachment
  • Pharmaceutical cleanroom-compatible labeling

Key Features

  • Adheres to low-surface-energy substrates where acrylics fail
  • Service temperature range -60 °C to +200 °C — widest in PSA category
  • Biocompatible grades: USP Class VI, ISO 10993 for skin contact
  • Residue-free removal after extended dwell at elevated temperatures
  • Stable tack and peel over wide humidity and temperature ranges
