While EVA hotmelts are an excellent solution for many industrial applications, the high temperature of the process needs to be carefully controlled to avoid smoke problems. When hot melt adhesives are heated, they inevitably release some fumes. That's the smell detected when working close to the hot melt nozzle. While some smoke is normal, too
The paper bag glue is not firmly bonded, and the carton is degummed. Degumming refers to the cracking of the adhesive mouth due to insufficient bonding fastness. The main reasons are summarized as follows: (1) The viscosity of the adhesive is insufficient or the amount of glue applied is insufficient. (2) The adhesive and the
Types of hot melt adhesives used in automotive hot melt adhesive dispensing: Most automotive hot melt adhesive dispensing processes have examples of use in automobiles, but different types of hot melt adhesives will be selected for different parts and uses. According to its function, it can be divided into two categories: bonding type and sealing
CASAPAO (AmorphousPolyAlphaOlefin) is referred to as APAO glue, which is a low-molecular-weight amorphous copolymer obtained by using a proprietary catalyst and using propylene and ethylene as raw materials. APAO is widely used in the following aspects: 1. For APP waterproof membrane. After modification of asphalt by APAO, it can improve the high temperature and low
We know that there are many kinds of mattresses, such as sponge mattresses, palm mattresses, spring mattresses and 3D mattresses. In the production process of these mattresses, there are many parts that need to use mattress adhesives, so when choosing an adhesive mattress When is there anything to pay attention to? The first point is
Paper bag glue is a professional adhesive for bonding polyethylene (P.E) and polypropylene (P.P) film paper. It is widely used in over-plastic carton, hand-held paper bag and the bonding between the surface of the matte glue and the glossy glue film and the paper. All paper and plastic materials are imported and made by high-temperature
If you want to paste the edge banding, you can directly use the hot melt edge banding adhesive to paste the edge banding. It itself belongs to a type of hot melt adhesive. The shape looks like particles. There are two main colors, one is yellow, and the other is pure white, which can be
Paper bag adhesive is a product with good initial adhesion, quick drying, high final adhesion strength, soft film, not brittle at low temperature, good flexural resistance, non-toxic, environmentally friendly, easy to use and good storage stability. Introduce what should be paid attention to when using paper bag glue. 1. The paper bag adhesive has strong
PVA polyvinyl acetate application glue Polyvinyl acetate is most often used for glue. German scientist Dr. Fritz first discovered polyvinyl acetate as a binder in 1912, and since then it has been widely used in the processing of porous materials such as wood and paper. Depending in part on the strength of this polymer, different
Polyvinyl acetate (Polyvinyl Acetate, PVAc) emulsion adhesive is prepared by emulsion polymerization of vinyl acetate (VAc) as a reactive monomer in a dispersion medium, also known as polyvinyl acetate emulsion, commonly known as white latex or white glue , is one of the varieties with the largest output in the synthetic resin emulsion. In 1929,
