Hydrogenated Terpene Polymer

HTR105

Foreverest® HTR105 is a kind of colorless or water white resin that has thermal stability and weather resistance.

It is a newly developed hydrogenated terpene resin. Hydrogenated Terpene Polymer is an excellent raw material for natural adhesives and also be used as additives to modify various plastics.

Application & Uses

Application
Adhesives & PSAs
  • Optically clear adhesives (OCA): good compatibility of hydrogenated terpene resins with styrenic block copolymers (SIS/SEBS) enables low-haze, high-transparency formulations for display lamination and premium protective films. Their low refractive-index fluctuation further enhances optical performance.
  • Hot-melt adhesives (SEBS/EVA/APAO): hydrogenated terpene resins markedly improve initial tack and bond retention under high-temperature reflow conditions. Their non-polar nature ensures perfect compatibility with PP/PE substrates, eliminating the phase-separation and recycling-contamination risks associated with polar tackifiers.
  • Hygiene and nonwoven applications: hydrogenated terpene resins optimise the viscoelastic profile of APAO/SEBS systems, balancing cold tack and heat-holding performance. In web bonding for nappies, sanitary pads and mask ear-loops, their low odour and low fogging residues enhance end-user experience.
  • Flexible electronics and wearable devices: hydrogenated terpene resins facilitate low-modulus, long-term-stable PSAs that offer skin conformability while their low migration tendency minimises potential interference with sensitive electronic components.
  • UV/EB-curable bonding: hydrogenated terpene resins synergise with acrylic PSA or radiation-curable systems to deliver rapid tack build-up and suppress photo-yellowing, meeting the demands of high-speed coating processes.
EV Vehicles
  • Green tyre formulations: deeply hydrogenated terpene resins significantly reduce light oil and aromatic content in new-energy-vehicle tyre and interior NVH (noise, vibration and harshness) sealant compounds, mitigating odour release and fogging during service. They also serve as processing aids that replace conventional aromatic resins, lowering volatile emissions and improving interlayer adhesion during mixing.
  • Battery-pack auxiliary materials: the thermal and ageing resistance of hydrogenated terpene resins enables them to withstand the complex thermal cycling environment within battery compartments, ensuring long-term reliability.
Electronics & Flexible Circuits
  • Flexible circuit boards (e.g. PI/PU systems): low dielectric constant, low moisture absorption and favourable interfacial wetting properties make hydrogenated terpene resins suitable as adhesive buffer layers.
  • Electronic encapsulation: outstanding thermo-oxidative and photostability effectively inhibit yellowing, enhancing long-term device reliability.
