PSA hot melt adhesive
PSA hot melt adhesive has emerged as a standout solution for numerous applications. This article aims to provide an in – depth exploration of this remarkable product, delving into its various aspects from product parameters to company background, all geared towards highlighting its exceptional advantages and encouraging potential customers to reach out to Adhesive (Shanghai) Co., Ltd.
Product Description
PSA hot melt adhesive, or pressure – sensitive adhesive hot melt adhesive, represents a cutting – edge adhesive technology. It is a type of adhesive that exhibits tacky properties at ambient temperatures and can form a bond when pressure is applied. What sets it apart is its unique formulation and characteristics that make it suitable for a wide array of industries.
This adhesive is composed of several key components. The base polymer plays a crucial role in determining its fundamental properties such as viscosity and elasticity. Common base polymers include ethylene – vinyl acetate (EVA), polyolefin, and polyamide. These polymers provide the adhesive with its inherent tackiness and strength.
Alongside the base polymer, tackifiers are incorporated to enhance the adhesive’s tackiness. They improve the adhesive’s ability to wet the substrate and form a strong bond upon contact. Additionally, plasticizers may be added to modify the flexibility and workability of the adhesive. They help in achieving the desired consistency and application characteristics.
The appearance of PSA hot melt adhesive can vary depending on its specific formulation and intended use. Generally, it comes in the form of granules or pellets, making it easy to handle and apply in various production processes. The color can range from transparent to slightly yellowish, allowing it to blend in with different substrates and applications.
Product Parameters
The product parameters of PSA hot melt adhesive are meticulously designed to meet diverse application requirements. Here are some key parameters:
-
Viscosity: Measured in centipoise (cps), the viscosity of the adhesive determines its flowability. For instance, a lower viscosity adhesive (in the range of 1000 – 3000 cps) is suitable for fine – line applications and porous substrates, as it can easily penetrate and fill in the pores. A higher viscosity adhesive (above 5000 cps) is more appropriate for applications requiring a thicker adhesive layer or on non – porous surfaces.
-
Open Time: This refers to the time during which the adhesive remains tacky after application and before it starts to solidify. The open time of PSA hot melt adhesive typically ranges from a few seconds to several minutes. It is influenced by factors such as temperature, adhesive thickness, and substrate type. A longer open time allows for more precise positioning of materials, which is beneficial in applications like label application where accurate alignment is crucial.
-
Set Time: The set time indicates how quickly the adhesive achieves sufficient strength to hold the bonded materials together. It can vary from instantaneous setting to several minutes. A shorter set time is advantageous in high – speed production lines where quick assembly is required, such as in the packaging industry for sealing products.
-
Peel Strength: Measured in units like N/25mm, peel strength reflects the adhesive’s ability to resist separation when a force is applied perpendicular to the bond line. PSA hot melt adhesives can offer peel strengths ranging from low values suitable for removable applications, like repositionable labels, to high values exceeding 100 N/25mm for permanent bonds in applications such as automotive trim attachment.
-
Temperature Resistance: Depending on the specific formulation, PSA hot melt adhesives can withstand a range of temperatures. Some are designed for low – temperature applications, maintaining their bond integrity even at temperatures as low as – 20°C, while others can endure high temperatures up to 200°C or more. This versatility makes them suitable for products that may be exposed to varying thermal conditions during usage or storage.

It begins with the careful selection and preparation of raw materials. The in – house produced raw materials are thoroughly tested for consistency and purity to guarantee the desired adhesive properties.
Once the raw materials are ready, they are fed into specialized mixing equipment. Under precise temperature and mixing conditions, the components are blended together to form a homogeneous adhesive mixture. The mixing process is closely monitored to ensure the proper distribution of each ingredient and to achieve the desired viscosity and rheological properties.
After mixing, the adhesive undergoes a melting and homogenization stage. The mixture is heated to the appropriate temperature to ensure complete melting and uniformity. Any impurities or air bubbles are removed during this process to enhance the adhesive’s performance and appearance.
The molten adhesive is then extruded into the desired shape and size, such as granules or pellets. The extrusion process is controlled to ensure consistent dimensions and quality of the final product. The extruded adhesive is cooled and packaged in protective containers to maintain its stability and prevent contamination during storage and transportation.
Throughout the entire production process, strict quality control measures are implemented at each stage.
