DOTP plasticiser
DOTP is dioctyl terephthalate, the main plasticiser for flexible PVC. It is what makes the resin pliable: without a plasticiser PVC stays rigid, and the higher the DOTP loading, the softer the finished part. Chemically it is a terephthalate rather than an ortho-phthalate, which is why it is chosen where the composition of the material is subject to separate requirements.

Standard requirements, not the test result of a particular batch.
Storage and transport
Store in closed containers under cover, away from fire and heat sources and out of direct sunlight. The flash point is 210 °C minimum, so the product is not classified as a flammable liquid.
