Urea formaldehyde adhesive powder is a type of adhesive that is commonly used in the woodworking and furniture industries for bonding wood and wood-based materials. It is a powdered resin that is typically mixed with water to form a glue-like substance for bonding purposes. Here are some key points about urea formaldehyde adhesive powder:
Composition: Urea formaldehyde adhesive powder is composed of urea formaldehyde resin, which is synthesized by the reaction of urea and formaldehyde. This reaction produces a thermosetting resin that is commonly used as an adhesive.
Powder Form: The adhesive is manufactured in a powdered form for ease of handling and storage. The powder is then mixed with water to form a workable adhesive solution.
Application: Urea formaldehyde adhesive powder is widely used in the bonding of wood and wood-based products, such as particleboard, plywood, and medium-density fiberboard (MDF).
It is suitable for applications where a strong and durable bond is required.
Curing Process: Urea formaldehyde adhesives are thermosetting, meaning that they undergo a curing process when exposed to heat and pressure. This process results in a cross-linked structure, providing a strong and durable bond.
Features: Urea formaldehyde adhesives offer good bonding strength, water resistance, and heat resistance.
They are cost-effective and have been widely used in the woodworking industry for many years.
Urea Formaldehyde Concentrate (UFC 65) is a clear and viscous liquid, composed of formaldehyde, urea and water. It provides high concentration of formaldehyde commercially available in an easy-to-use form.
Applications
It is used in production of aminoplast resins such as urea formaldehyde adhesives, UF and MUF impregnation resins.
It is used as anti-caking agent in the process of urea production.
Urea formaldehyde is a type of thermosetting resin that is produced by the reaction of urea and formaldehyde. This resin is commonly used in the production of adhesives, particularly for wood products such as particleboard, medium-density fiberboard (MDF), and plywood. The resin provides excellent bonding properties and is valued for its water resistance and durability.
Urea Formaldehyde Concentrate (UFC 85) is a clear and viscous liquid, composed of formaldehyde, urea and water. It provides high concentration of formaldehyde commercially available in an easy-to-use form.
What is PET Open Agent Film Chips?
PET Open Agent Film Chips are plastic chips made of polyethylene terephthalate (PET) that contain an open agent, which helps to improve the adhesion of inks and coatings to the surface of the film.
It is uniformly depressed anti-adhesive, with excellent film-forming properties; polymerization of continuous device production makes the quality high and stable.
As an opening agent to be used with film grade base materials to produce various types of films.
It can be used in films with special requirement for optical and surface properties or ultra-films below 8u.
Can be used directly in foodstuffs after FDA approval.

Low Melting Point Polyester Chip for Hot Melt Yarn Masterbatch
Extrusion Grade Polymer for Hot-melt Adhesive Glue Coating
Description:
Generally speaking, the low melting point polyester chip refers to one specialty polymer with a melting point between 90 and 220.
The melting point of polyester is the temperature at which a solid crystalline substance changes from a solid state to a liquid. So it reflects the purity of polyester. Generally speaking, pure polyester is a partially crystalline polymer with a melting point of 265. But during actual production, some impurities exist in the polyester due to various side reactions. At the same time, the defects of polymer crystals and the difference in crystallinity will also affect the melting point. The common type of low melt polymer is 110. But we can also offer a melting point of 90, 120, 160, and 180.
Application:
Low-melt polyester chips can produce low-melting point fiber, low-melting point synthetic fiber, and thermal-melting mucilage. Its primary usage is acting as bonding fiber in nonwoven fabrics. The end usage lies in clothing, articles for bed, shoe uppers, sleeping bags, sofas, and hygiene products.
LM PET Chip is also the main raw material of masterbatch carriers. That is, low-melt PET chips, conventional chips, and dyes are mixed to produce the polyester color masterbatch according to a certain proportion. The production of this product is the introduction of polyester macromolecules into the modified copolymer unit. And its melting point is in the range of 100-120. Commonly used modifiers are phthalic acid, adipic acid, and trimethylolpropane.
Recently, LM Polymer is also extruded into the back coating of nonwoven, automotive interiors, foam, injection molding, PET sheets, and hot-melt adhesive/glue.
Low Melt Yarn is also called hot melt yarn or fusible yarn. There are sheath-core low-melt bicomponent yarn and full low-melt polyester yarn.
