KURARAY LIQUID RUBBER - Elastomer Division | Specialty Chemicals
This type of KURARAY LIQUID RUBBER has many uses, including tires, printing plates, automotive sealants, coatings, adhesives, hot melt adhesives and pressure sensitive adhesives (PSA). It can also be used as a coagent for EPDM (peroxide curing) and for thermoset PU modification. L-BR-302 | L-BR-307 | L-BR-305 High Vinyl LBR
Specialty Plasticizers for Rubber/Elastomers | Hallstar
Normal service temperatures are -40°C to 125°C, but special compounding can broaden this range to -55°C to 150°C for intermittent service. The elastomer requires antioxidants, anti-ozonants, fungicides, plasticizers, tackifiers and flame-retardants as the occasion and severity of the application demands.
Mesamoll | The universal plasticizer | LANXESS
Some plasticizers develop a high potential regarding scope of use, but they are designed for a specific use. Unimoll AGF, our largely bio based plasticizer, was developed for the use in articles intended to come into contact with foodstuffs. Our Uniplex Benzoates are mainly solid special plasticizers used in hot-melt adhesive & equipment
Plasticizers & Processing Aids - HM Royal
Processing aids and plasticizers are chemical additives used in compounds to increase the plasticity, fluidity or lubrication of a material. These processing aids are suitable for use in plastics and rubber compounds. Plasticizers soften polymer compounds in order to improve processing, lower compound viscosity and increase the flexibility of
Plasticizer Selection for Elastomers - Chemceed
Plasticizers can be added to elastomers for various reasons: increasing softness or flexibility, lowering the glass transition temperature, reducing crystallization, increasing dispersion, or lowering the cost of the compound. Common plasticizers used in elastomer compounds are mineral oils and esters such as phthalates, sebacates, and adipates.
- What plasticizers are used in hot-melt extruded systems?
- Although commonly used pharmaceutical plasticizers such as triacetin, 4 citrate esters, 2, 5 and lower molecular weight polyethylene glycols 2, 3, 4 have been investigated in hot-melt extruded systems, almost all of them are liquid.
- Are plasticizers effective as processing aids for HME process?
- The physical and mechanical properties of plasticizers, in selected binary (polymer:plasticizer) and ternary (active pharmaceutical ingredient:polymer:plasticizer) systems, were evaluated to assess their effectiveness as processing aids for HME process.
- What is a solid state plasticizer?
- Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers. Binary and ternary physical mixtures were evaluated as a function of plasticizer concentration for thermal and rheological behavior.
- How are plasticizers classified?
- Plasticizers are classified according to their molecular structure into monomeric or polymeric types. The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use.
- Which solid-state plasticizers are used in a chemistry study?
- Solubility parameters, thermal analysis, and rheological evaluation were used as assessment tools. Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state 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.
