Plasticizer – HB Chemical
Plasticizers are substances that are added to a compound to make that material softer and more flexible by decreasing its viscosity. This is done to either make the material easier to process and handle during manufacturing or to facilitate a specific need or performance for the end product.
Long- and short-term stability of plasticized poly(lactic acid
In addition, a new plasticizer, PEG-functionalized polyhedral oligomeric silsesquioxane (PEG-POSS), was used for comparison. The short- and long-term mechanical, thermal, and morphological properties of PLA and plasticized PLA were determined by tensile tests, differential scanning calorimetry, and scanning electron microscopy (SEM), respectively.
A highly stable bio-based plasticizer constructed from renewable acids
The current research efforts in the plasticizer industry should focus on finding renewable biomass chemical feedstocks to synthesize non-toxic and effective bio-based plasticizers in order to adapt to the concept of green environmental protection given the scarcity of petroleum resources and the growing emph
Plasticizer - an overview | ScienceDirect Topics
Good plasticization involves interspersing plasticizer molecules between PVC chains, breaking the small amount of native PVC crystallinity, and internally lubricating the polymer blend. While there is no formal chemical bond between plasticizer and polymer, the polar attraction between them makes plasticized PVC more than a simple physical mixture.
Selecting Tackifiers for Adhesives and Sealants
Hydrogenation is primarily used to improve color and stability of the resin by removing vulnerable double bonds. Partial and selective hydrogenation are methods used to produce resins with broad compatibility and good stability. The most common base resins used for hydrogenation are as follows: C9 resins C5 resins DCPD and modified DCPD resins
- Which plasticizer is most stable after 10 d?
- After 10 d, the migration trend of all samples had been stabled, it showed that the traditional plasticizer like DOP, DOTP and DOA had basically move out from the PVC matrix in non-polar environment due to their own single structure, while the PVC plasticized with A-ODL showed the best stability in all the environment.
- Can ricinoleic acid make a high-stability bio-based plasticizer?
- In this work, a new type of high-stability bio-based plasticizer was obtained by a four-step reaction with ricinoleic acid as main raw material, and its structure was characterized and identified by FT-IR and 1 H NMR.
- Which plasticizer is used to make polyvinyl chloride (PVC) films?
- Subsequently, ricinoleate plasticizer, commercially available dioctyl phthalate (DOP), and bis (2-ethylhexyl) adipate (DOA) were added to prepare polyvinyl chloride (PVC) films for performance comparison.
- What are biodegradable plasticizers?
- Biodegradable plasticizers such as soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were added to poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films, enhancing their thermal and mechanical properties. TEC or DBP presented better plasticizing effects than SO and ESO for PHBV .
- Which plasticizer has the best mechanical properties?
- Of the plasticizers we synthesized, the best film mechanical properties were provided by OC plasticizer, containing primarily propylene glycol monoacetate, but also propylene glycol diacetate, acetic acid and propylene glycol in its mixture.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
