Dibenzoate Plasticizer Technology
Dibenzoate Plasticizer Technology for Sealants Source Dibenzoate plasticizers are widely utilized in latex caulks because they are compatible with the polymers used in that application. Dibenzoates are also known to be used in the polymer side of two-part insulating glass polysulfide sealants.
Plasticizers - ASTM International
Plasticizers are primarily employed in heavy gage coatings and/or when improved toughness is required for industrial, automotive, and appliance applications. Plasticizers function by reducing the glass transition temperature of the resin to a point below its application temperature.
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.
New standard test method to identify plasticizers | Food
On June 6, 2013 the developer of international voluntary consensus standards ASTM International released a new standard test to determine low level migration of phthalates. The method aims to ensure compliance with the U.S. Consumer Product Safety Improvement Act (CPIA) of 2008, Section 108, which prohibits certain products, including toys, from containing 6 phthalates. The
Standards used for polyethylene pipe - TWI
ASTM F876-15a Standard specification for cross-linked polyethylene (PE-X) tubing. ASTM F877-11a Standard specification for cross-linked polyethylene (PE-X) plastic hot- and cold-water distribution systems. ASTM F894-13 Standard specification for polyethylene (PE) large diameter profile wall sewer and drain pipe.
- How many high boiling fluids are a plasticizer?
- Several thousand high boiling fluids are potential plasticizers for coatings applications. The choice of plasticizer is dependent on compatibility with the resin in use, cost, and other desired attributes. Plasticizers may be classified by both chemical structure and performance characteristics, as shown in Table 1 .
- Which plasticizers can be volatilized?
- Due to the need to volatilize the plasticizer, only monomeric plasticizers having definitive boiling points and a molecular weight less than 1000 Daltons, such as dioctyl phthalate, are applicable to this guide. 1.2 The values in SI units are to be regarded as standard.
- Why do we use high boiling fluids as plasticizers?
- Access your content now. PAINT AND COATING FORMULATIONS OFTEN incorporate high boiling fluids as plasticizers where rigid or brittle resins fail to meet toughness and flexibility requirements. The primary function of the plasticizer is to impart flexibility to the resin, thus minimizing film cracking.
- What if area percent of plasticizer is less than 99 %?
- However, if the area percent of the plasticizer is less than 99.0 % or if any question were to arise about the data, an internal standard shall be used. 5.3 Impurities potentially found in monomeric plasticizers include alcohols, dibasic acids, and monoesters.
- What is a plasticizer used for?
- Plasticizers are primarily employed in heavy gage coatings and/or when improved toughness is required for industrial, automotive, and appliance applications. Plasticizers function by reducing the glass transition temperature of the resin to a point below its application temperature.
- How are plasticizers delivered?
- Methods for the isolation, identification, and quantitative determinations of these plasticizers are also included. Domestic orders are delivered via United Parcel Service (UPS) or United States Postal Service (USPS). Transit times average 3 to 5 business days. Please be aware that UPS will not deliver packages to Post Office Boxes.
