Polyterpene resin
Key properties
This resin, produced from d-limonene, a natural terpene of citrus origin, is characterized by its light color, resistance to aging, high thermal stability, and excellent balance of tack, adhesive and cohesive properties.
It is a highly effective tackifier for both elastomeric- and thermoplastic-based adhesive systems, particularly pressure-sensitive and hot-melt types.
It is also excellent as a mid-range softening masticatory agent and binder in chewing gum compositions.
- Tackifier resin with natural and synthetic rubbers in pressure-sensitive and hot-melt adhesives

Pastillated or flaked resins may fuse, block, or lump during hot weather months, if stored near sources of heat, if double or triple stacked, or if stored for prolonged periods of time.
These forms of resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or could have an adverse effect on solubility in organic solvents.
Care should be taken to minimize opportunities for product oxidation throughout processing. Accordingly, we strongly recommend maintaining proper storage conditions and strict inventory control at all times, ensuring that the oldest material is used first.
