Hallstar | Innovative, leading-edge, ester chemistry solutions
New polymeric esters from Hallstar have been specifically designed to be highly compatible with low ACN (H)NBR, EPDM, TPV, TPO, PE and PP polymer compounds. The polymeric nature increases modifier permanence without sacrificing low temperature and general mechanical performance.
PLASTICIZERS FOR ENVELOPE ADHESIVES - Hallstar Industrial
envelope, in both the manufacturing process and during the service life of the envelope. TYPES OF ENVELOPE ADHESIVES In the U.S., general purpose, commercial envelopes use two different types of adhesives. Envelopes which contain a “window” utilize the same two types of adhesives and also employ a third type of adhesive to hold the window
Selecting Plasticizers for Adhesives and Sealants
Plasticizers are one of the commonly used additives in adhesives and sealants formulations. They improve the performance of adhesives by creating much-needed flexibility, optimizing viscosity, toughness, set time functionality, impact resistance, and even adhesion.

- Who is hallstar chemistry & polymer compatibility?
- Hallstar has a long history of providing leading-edge chemistry solutions in all types of polymers, and we are experts in renewable ester chemistry and polymer compatibility.
- What is a standard monomeric plasticizer?
- he following:Standard Monomericsare typically low molecular weight, general purpose products offering a good balance of performance properties for on-critical end use applications. These plasticizers generally fall under our Plasthall® trade name, suc
- What is a Hallgreen® ester?
- One of our newest product lines is the HallGreen® collection of environmentally responsible renewable esters for use in PLA, PHA, PSM and other bio-polymers. These esters are biobased and derived from renewable raw material streams. HallGreen® products function as process aids, polymer and impact modifiers.

Plasthall®, TP-95®, TP-90B®, TegMeR® and Sulfur Spider® are Rubber (NBR)POLYMER INFORMATIONNitrile elastomers (NBR) result from reactions of butadiene and acrylonitrile (ACN) monomers. ACN content ranges from a high of about 50 per ent to a low of about 18 percent. Available grades have approximat
- Are polymeric plasticizers effective?
- ect cure rate and degree of cure. Plasticizers containing double bonds (oleates and tallates) can rob curative effe tiveness, as can naphthenic oils. Generally, polymeric plasticizers do not provide significant performance advantages ov monomerics and are seldom used.
