Selecting Tackifiers and Plasticizers for PSA Formulations
Best combine plasticizers & tackifiers for optimal pressure sensitive adhesives performance. Ed Petrie will map current chemistries and share a systematic testing procedure to choose plasticizer and tackifiers for your PSA as well as solutions to maximize performance by balancing the plasticizer / tackifier couple.

KURARAY LIQUID RUBBER - Elastomer Division | Specialty Chemicals
KURARAY LIQUID RUBBER as a reactive plasticizer Depending on molecular weight (MW), KURARAY LIQUID RUBBER can act as rubber replacement or as a reactive plasticizer. KURARAY LIQUID RUBBER is cross-linkable with base rubber and acts like a process oil, but does not bleed. Content Features and benefits / applications Types of KURARAY LIQUID RUBBER
Dibenzoate Plasticizers in Waterborne Acrylic PSAs
One tackifier dispersion was selected that has a T g of about 35°C and a softening point of 85°C. The plasticizer selected for the study was the triblend of dibenzoate plasticizers described previously, which will herein be abbreviated as 975P.
Selecting Tackifiers for Adhesives and Sealants
Tackifiers can be derived from natural or petroleum feedstocks and they are divided into three main groups: Hydrocarbon resins Rosin resins, and Terpene resins Although the natural tackifying resins represent the oldest technology, a recent increase in interest has occurred in these products due to the emphasis on bio-based, green additives.
Hydrogenated DCPD-Based Resins for SBC-Based Hot-Melt PSAs
Tackifiers having an aromatic H wt% higher than 3% and/or a softening point lower than 110°C have significant loop tack strength at room temperature; SU-490, SU-400, H-2300 and SU-90 are examples of such tackifiers.

- What is tackifier & plasticizer?
- Due to the molecular property of the resin the tackifier quicky travels to the substrate on the compound providing the much needed building tack. Plasticizer: These resins contribute as plasticizers during the compound of the rubber compound.
- What are Tackifiers used for?
- In adhesive and sealant formulations, tackifiers are used to generate tack and improve specific adhesion (peel strength). They are incorporated into base polymers which mainly lack tackiness and pressure-sensitive properties but provide cohesion.
- What are Tackifiers & plasticizers in PSAs?
- Source: Extance, A., “Using Tackifiers and Plasticizers in PSAs”, SpecialChem, February 9, 2009. Plasticizers are organic liquids or solids that are incorporated by melt processing or diffusion into a compatible polymer to reduce interaction between molecules and improve molecular mobility.
- Where are mexiflex® plasticizers made?
- Under the brand MEXIFLEX®, we produce plasticizers for PVC compounds at our facility in Altamira (Mexico). We also produce phthalic anhydride. Vertical integration allows us the flexibility to manage the supply chain. It also gives us the innovative ability to create materials to our exact specifications.
- What is the best tackifier resin?
- With more than 35 years of experience, and 30+ grades in AP Series we offer resins to a wide spectrum of Industries. POLYTONE® AP 121 and AP 121 H are our best offering as tackifier resin, these are Octyl Phenol based Novolak Resins which provide superior green tack along with added benefits of low colour and plasticizer properties.
- What is tackifier resin dispersion?
- In certain cases, resins that are liquid at room temperature are dispersed as well. Tackifier resin dispersion can be mixed into the polymer dispersion easily. The amount and type of emulsifiers used are the main factors for storage stability, compatibility, and coatability.
