Dioctyl Terephthalate is a non-toxic plasticizer that can replace ortho-phthalates in PVC

DOTP is a non-toxic plasticizer that can replace ortho-phthalates in PVC. It is a general-purpose plasticizer suitable for film & sheet, calendaring, slush molding, dip molding, rotational molding, and injection molding. It is also compatible with halogenated solvents.

DOTP is produced from terephthalate polyesters such as PET using degradative transesterification. It is inexpensive, environmentally friendly, and easy to produce.

It is a phthalate-free plasticizer

Phthalate-free plasticizers are widely used in manufacturing products that require flexibility, such as vinyl floorings, electrical connectors, and vinyl water stops. They are also used to manufacture toys, bottle caps, and medical equipment. Phthalates are harmful to the environment and have been linked to many health problems. They are also known to cause damage to the immune system, gastrointestinal tract, reproductive organs, and brain.

The most commonly used phthalate-free plasticizers are di (2-ethylhexyl) terephthalate (DEHT), diisononyl terephthalate (DINCH), and butyl benzyl phthalate (BBzP). However, toxicity information for these chemicals is limited. Detection rates of DEHT and DINCH in urine have increased with their use as replacements for ortho-phthalates, suggesting that chronic exposure to these chemicals may affect human health.

DOTP is a colorless viscous liquid that is used to soften PVC plastics. It is a safer alternative to ortho-phthalates and can be used in the manufacture of high-temperature cables, automotive plastic parts, and senior leatherette. It is also used in paper finishing, calendaring, extrusion, injection molding, rotational molding, dip molding, and slush molding. It offers excellent low-temperature resistance and durability.

It is a PVC plasticizer

Dioctyl terephthalate (DOTP) is an essential phthalate-free plasticizer used in the manufacturing of PVC. It has excellent performance and a low migration rate. It is a clear, colorless liquid with a faint odor that is insoluble in water. It is also known as di (2-ethylhexyl) terephthalate or Eastman 168TM.

The toxicity of this plasticizer is less than that of the ortho-phthalates it replaces and does not cause peroxisome proliferation of liver enzymes. It is also used in applications that require low phthalate content, such as paper softeners, polyester amide biaxially stretched films, and plasma storage bags.

This phthalate-free plasticizer can be extracted from scrap terephthalate polyesters by degradative transesterification. This technique allows for a more economical production method while decreasing solid waste and environmental concerns. It is also effective at improving extraction resistance from PVC composites into hexane, soapy water, and mineral oil. However, it may decrease tensile strength and elongation at break. Furthermore, it can reduce tear resistance.

It is a PVC softener

Dioctyl terephthalate is an important phthalate-free plasticizer for PVC. It is a clear, colorless liquid that is insoluble in water and has a slight odor. It is used to plasticize PVC in plastisols and shows good performance in products with durability, low temperature flexibility, and electrical resistance. Unlike lower-chain phthalates, it does not promote chemical migration.

It is a good alternative to DOP, which can be a health risk. It can also be used in food containers and packaging materials, as it is non-toxic and biodegradable. It is not a fire hazard, but it may decompose to a toxic gas under high temperatures. It should not be exposed to flames or direct sunlight.

Aliphatic esters derived from adipic, azelaic, and sebacic acids esterified with linear or branched monofunctional alcohols are the primary plasticizers in PVC. They have a low viscosity and extend the lifetime of PVC end-products significantly. The migration of these plasticizers to the human body can be a health risk, especially in women who are pregnant or breastfeeding. Conventional migration tests are performed at a fixed time and temperature, but these do not account for variation in the rate of migration with respect to the surface layer of the skin, which is covered by sebum.

It is a PVC stabilizer

The main purpose of a PVC stabilizer is to protect the polyvinyl chloride (PVC) from degradation under conditions of thermal, weathering, and light. The stabilizing agent is added to the raw materials before processing into PVC, and it can reduce or eliminate PVC degradation due to a variety of factors. Besides, it can prevent loss of plasticizers during the manufacturing process.

PVC stabilizers can be used in a variety of processes, including extrusion and injection molding. They are a safer alternative to phthalate-based plasticizers and provide improved flexibility, low temperature resistance, and durability.

The different compositions of tannin-Ca complex showed that this derivative can act as both primary and secondary plasticizer for PVC, enhancing the compatibility with Zn
