Designing Green Plasticizers: Linear Alkyl Diol Dibenzoate
The C3, C5, and C6 dibenzoates performed as well as or better than DEHP, with the exception of torsional modulus, further supporting their use as green plasticizers. For blends with 1,4-butanediol dibenzoate, differential scanning calorimetry and torsional temperature sweeps suggested that the compound partly crystallizes within PVC blends over
K-Flex | Optimized plasticizers | LANXESS
K-FLEX : Environmentally-friendly plasticizers that deliver value. K-FLEX plasticizers optimize your manufacturing processes and the properties of your end-products. They are highly compatible with polar polymers in water-based adhesive systems and they improve the film formation of paints and coatings.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
Synthesis of a New Benzoate Plasticizer for Polyvinyl
The heavier bottoms fraction enriched in diol (1) (diol fraction) can also be used as a cheap raw material for plasticizer synthesis.In the industry, based on glycols, predominantly dibenzoate plasticizers (for example, the trade mark Benzoflex) are produced, which are utilized as secondary solvating plasticizers in polyvinyl chloride compositions.
Plasticizer Migration: Ensuring Safety in Food Packaging
The plasticizer of focus is propylene glycol dibenzoate (K-FLEX PG). When blended with two traditional dibenzoates, it is part of a product called K-FLEX 975P. PG has 21 CFR 175.105, but not 21 CFR 176.170. The other plasticizers in the blend are dipropylene glycol dibenzoate (DP) and diethylene glycol dibenzoate (DE).
- Which polymers are compatible with dibenzoate plasticizers?
- Compatibility with a variety of polymers and applications. Dibenzoate plasticizers are compatible with many polymeric materials, including ethylene vinyl acetate (EVA), polyvinyl chloride (PVC), styrene-butadiene rubber (SBR), ethyl cellulose (EC), nitro cellulose (CN), cellulose acetate butyrate (CAB), polyurethane (PU) and acrylics (PMMA).
- What is a dibenzoate plasticizer?
- Dibenzoate plasticizers are highly solvating monomeric plasticizers that decrease processing times and lower processing temperatures. In addition, they offer superior resistance to extraction by solvents such as kerosene, cotton seed oil and soapy water.
- What is dipropylene glycol dibenzoate?
- It is a high-solvating plasticizer containing mostly dipropylene glycol dibenzoate. It is used in a wide variety of applications, including caulk, adhesives, resilient flooring, PVC-coated fabrics and artificial-leather cloth. In PVC, it acts as a medium- viscosity high solvator that saves energy and improves process ability.
- Are dibenzoate plasticizers better than phthalates?
- From a health and environmental perspective, the European Chemical Agency (ECHA) listed dibenzoate plasticizers as a preferred alternative to phthalates in May 2009. Certain grades of dibenzoate plasticizers are more environmentally friendly than others. Many require no warning labels and are even approved by the FDA for use in food packaging.
- Is velsiflex a plastisol?
- As a vinyl plasticizer, Velsiflex® has the solvating power that affords ample formulating latitude for optimized PVC formulations. Typical plastisol applications include calendering, flooring, or automotive plastisol sealants. Velsiflex plasticizers are high performance plasticizers. They are polar and monomeric in nature.
- What are velsiflex plasticizers?
- Velsiflex plasticizers are high performance plasticizers. They are polar and monomeric in nature. In most cases, they provide superior performance compared to other plasticizers as it relates to polymer compatibility, efficiency and desired softness.
