Common faults and solutions of plastic pipe extrusion line-1 During the production line of plastic pipes, due to various reasons such as the operator's unskilled craftsmanship and machine operation, the plastic pipes often appear rough on the outer surface, jitter rings appear inside, uneven wall thickness, and insufficient roundness. Therefore, it is necessary to adjust the process in time and eliminate the failure of the plastic pipe ex…

Nitrogen FRs This class consists of pure melamine, melamine derivatives, i.e. salts with organic or inorganic acids such as boric acid, cyanuric acid, phosphoric acid or pyro/poly-phosphoric acid, and melamine homologues. Combinations of nitrogen-based flame retardants such as melamine polyphosphate and metal phosphinates also demonstrated flame retardancy of composites that has repercussion…

Phosphorous based FRs (PFRs) Phosphorus flame retardants (PFRs) (organic and inorganic) are more environmentally friendly, good thermally stable and have superior performance, resulting from the synergistic effect of P-N. They do not tend to form toxic gases since phosphorus is mostly locked into the char. Phosphorous FRs may be reactive (chemically bound) and additive (physical mixing) [2]. Lanxess [3] has…

Halogen-based flame retardants (Br-FRs) The Stockholm Convention (2001) listed 23 organo-halogen chemicals (including all BFRs) to be banned globally. The challenges of finding substitutes for banned halogen-containing flame- retardants include:A. Lower flame retardancy: Only 10 wt% of BFRs is equivalent to about 30-50% by wt of inorganic FRsB. High cost: Inorganic FRs is low-cost but require high loading. New HFFRs, …

Applications of Metallic Stearates-1 Properties of metallic stearates due to the unique structure of having polar and non-polar nature in the same molecule can be used in various functions in a variety of applications. They work as reactive processing aids, inert process enablers, mold release agents, acid scavenging agents, dispersing agents, and hydrophobizing agents. Here are a few applications where metallic st…

WHAT DO FLAME RETARDANTS DO? Flame retardants are a tool that can have a favorable effect on every key fire property, including ignitability, flame spread, heat release, and ease of extinction; albeit they do not necessarily have all of these effects simultaneously in every case. Some examples follow associated with well-known products in actual use where the effectiveness of the appropriate flame retardant…
