High-purity hydrogen-terminated polydimethylsiloxane (H-PDMS) with controlled molecular weight distribution.
Low volatility and excellent thermal stability up to 200 °C in inert atmospheres.
Reactive Si–H functionality enables efficient hydrosilylation with alkenes, alkynes, and functional silanes.
Consistent 30 cSt kinematic viscosity at 25 °C ensures reliable processability in coating, impregnation, and catalyst formulation.
Low color (APHA < 10) and high clarity support optical and electronic-grade applications.
Key crosslinker in platinum-catalyzed liquid silicone rubber (LSR) formulations for medical and automotive parts.
Surface modifier for silica and metal oxide nanoparticles to enhance dispersion and compatibility in composites.
Intermediate in synthesis of silicone surfactants, release agents, and functional siloxane polymers.
Hydrosilylation-based encapsulant and conformal coating material for LEDs and microelectronics.
Controlled reactivity platform for specialty adhesives, pressure-sensitive adhesives (PSAs), and anti-foam additives.
