Polymer additives range includes flame retardants and plasticizers.


Flame retardants based on phosphoric acid phosphoric acid, any one of three chemical compounds made up of phosphorus, oxygen, and hydrogen (see acids and bases). The most common, orthophosphoric acid, H3PO4, is usually simply called phosphoric acid.  esters are said to satisfy virtually all chemical and technical product requirements. Areas of use include materials for the construction, electrical and automotive industries. The Levagard range of flame retardants is said to be particularly suited for use in rigid polyurethane foams and thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic.  materials. The halogen-free Levagard DMPP DMPP Dimethylphenylpiperazinium

 was developed specifically for use in rigid polyurethane foams. This low-viscosity product with a phosphorus content of more than 20% can be used to replace either all or some of the halogen-containing flame retardant typically used in formulations.

Halogen-free esters of phosphoric acid in the Disflamoll line are used as flame retardants for all types of polymers. Used in PVC PVC: see polyvinyl chloride.

Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide.
, for example, they can be used to produce various flame-retardant items such as films or coated textile tarpaulins. Conveyor belts, v-belts and cable sheathing made from synthetic rubber are further examples of applications in which Disflamoll is said to come into its own as a flame retardant with a plasticizing effect.

Officially approved structural components, such as strips, mats or bricks, can be produced using the two-component Bayfomox raw materials system as a form of fire prevention, sealing up openings made in walls to pass through cabling or pipes. When subjected to high temperatures, the moldings foam to produce a heat-insulating carbon foam which prevents the breakthrough of fire and also smoke gases over a long period.

Plasticizers plasticizers

mostly triaryl phosphates, such as tricresyl, triphenyl phosphates, which are poisonous. See also triorthocresyl phosphate.
 are said to optimize the processing properties of polymer materials and give them improved quality or even new properties. The tried and tested plasticizer Mesamoll is a saponification-resistant ester of alkane alkane (ăl`kān), any of a group of aliphatic hydrocarbons whose molecules contain only single bonds (see chemical bond). Alkanes have the general chemical formula CnH2n+2.  sulfonic acid which is particularly compatible with a variety of polymers such as rubber, PU and PVC, according to the company.
