How is Erucamide made?
Erucamide is a primary amide and is synthesized by reacting erucic acid with gaseous ammonia. Behenic acid is synthesized by hydrogenation of erucic acid, which is further reacted with ammonia to produce behenamide. It offers anti-blocking and slipping properties that maintain polyolefin films clarity.
What is Erucamide used for?
This type of product is used principally as a slip additive, an antiblock agent, and for paper-coating compositions and water-proofing. Erucamide and some of its derivatives are approved for use in polymers at low concentration levels.
What is Erucylamide?
Description. Erucamide is a primary fatty amide resulting from the formal condensation of the carboxy group of erucic acid with ammonia. It is commonly used as a slip additive in the plastic manufacturing industry.
What is slip additive?
Slip additives are products which can be added to polymers to control friction. They are added directly into the polymer during the extrusion process and migrate to the surface as the polymer cools, allowing a solid lubricating layer to form.
What is Crodamide?
Crodamide OR (Powder) is a primary amide additive in powder form which produces excellent slip performance in polyolefins. Crodamide OR (Powder) quickly migrates to the surface of the polymer to form a thin lubricating layer.
What is slip and antiblock?
The slip and antiblock effects are confined to finished plastic parts, often from the range of polyolefins. Slip properties enable two surfaces to slide more smoothly over each other, e.g. for easier opening of screw tops. In contrast, antiblock properties reduce the adhesion of two surfaces.
What is plasticizer in PVC?
Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer.
What is an antiblock additive?
An antiblock additive present in the resin microscopically protrudes from the film surface. This creates asperities (i.e. “little bumps”), which help to minimize the film-to-film surface contact, increasing the distance between the two layers, thereby minimizing blocking.
What is antiblock?
Anti-blocking is a term used to describe measures to prevent film sheets to stick together. By that measure a micro-rough surface is created, and contact area of film layers is minimized; the distance between the layers is maximized and adherence suppressed.
What is a slip additive?
What is plasticizer made of?
What are they made of? Plasticizers are produced by a reaction of an alcohol with an acid such as adipic acid, phthalic anhydride, and so forth. The choice of alcohol and acid will determine the type of ester that can be produced and hence the kind of plasticizer.
Why is plasticizer used during Moulding of plastics?
Plasticizers are unique types of additives. Without plasticizers, a majority of the injection molding compounds would have been completely unfit for that purpose, and certain blends of rubber would not have been produced at all. Plasticizers make plastics elastic, extensible, flexible, and plastic at low temperatures.
Which is the home structure of erucamide molecule?
Home Structure ERUCAMIDE. A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. The ERUCAMIDE molecule contains a total of 66 bond(s) There are 23 non-H bond(s), 2 multiple bond(s), 19 rotatable bond(s), 2 double bond(s) and 1 primary amide(s) (aliphatic).
What kind of material is erucamide used for?
Polyamide is a polymer containing repeated amide groups such as various kinds of nylon and polyacrylamides. Erucamide, unsaturated long chain carboxylic acid amide (22:1 n-9), is used as a slip agent , anti-fogging or lubricant for plastic films (polyolefin) which can be used in food packing material.
What is the solubility of erucamide in water?
From the ratio of estimated vapor pressure and estimated Henry’s Law constant, the water solubility of erucamide has been estimated to be 0.2 mg/L(2). Since erucamide is a long chain aliphatic amide, it is likely to have low water solubility.
