Eastman Plasticizers for Adhesives
Admex 6995 is a medium molecular weight, light colored, polymeric adipate with a mild ester odor. Benzoflex 9-88 is a high solvating benzoate ester plasticizer that can be used in a wide variety of polymer systems and applications. Its diverse uses include resilient flooring, adhesives, caulks, and sealants.
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.
Phthalates in Food Packaging and Food Contact Applications
This function in the manufacturing of plastics is often referred to as a “plasticizer.” Some phthalates may be used in food packaging or other minor food contact uses such as components of...
Plasticizer use in Adhesives and Sealants - Chemceed
Plasticizers are an important component of many adhesives and sealants. A plasticizer is an additive used to increase flexibility or workability of a polymer system. Plasticizers typically affect the viscosity, lower the glass transition temperature, and lower the elastic modulus of a product.
Technical tip Plasticizer formulation - Eastman Chemical Company
plasticizers in various types of caulks and sealants. Some plasticizers are the primary recommendation for specific systems. Others are only effective in certain formulas, and some have more than one plasticizer that is suitable for a certain application. Table 2 Plasticizer recommendations for adhesives and sealant applications
- Why should you choose a plasticizer that is compatible with polymer?
- By choosing a plasticizer that is compatible with the polymer, it protects the plasticizer for leaching out of the product and thus losing the benefits of plasticization. Plasticizer permanence, or resistance to migration out of the adhesive or sealant, plays a role in the longevity of a product.
- What is a base polymer?
- Base polymers include the mid-blocks of styrene-butadiene copolymers and polyolefin-based adhesives. Polymeric plasticizers are used frequently in adhesives and sealants. These are similar to the base polymers and do not have the volatility problems associated with traditional plasticizers.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- What types of plasticizers are used in adhesives & sealants?
- Oils (like paraffinic, naphthenic, and aromatic) are used mainly as plasticizers in non-polar adhesives. These are generally used in the hot-melt adhesives and sealants. Base polymers include the mid-blocks of styrene-butadiene copolymers and polyolefin-based adhesives. Polymeric plasticizers are used frequently in adhesives and sealants.
- Can a polymer be plasticized?
- Almost all types of polymers can be plasticized. However, the plasticizer must be compatible with the base polymer in a formulation to function efficiently. The plasticizer and polymer should have similar polarity to produce compatibility. Often the solubility parameter of the polymer and that of the plasticizer is matched to provide compatibility.
- What is a plasticizer used for?
- A plasticizer is an additive used to increase flexibility or workability of a polymer system. Plasticizers typically affect the viscosity, lower the glass transition temperature, and lower the elastic modulus of a product. Phthalates and terephthalates are an example of effective plasticizer chemistries used in caulks and sealants.
