What is PE Wax?

PE wax, or polyethylene wax, is a multi-purpose synthetic wax that comes from either the polymerization of ethylene or as a by-product in the production of polyethylene. It can be provided in several forms such as flakes, powders, and granules. Due to this different presentation, this product is applied for numerous industrial uses. Usually, types of PE wax include HDPE (high-density polyethylene) and LDPE (low-density polyethylene). With very high performance in demanding applications, it finds broad appeal in several industries: plastics, coatings, adhesives, and rubber processing.

History of pe wax

physical and chemical Properties

Physical Properties:

• Hardness and Toughness:   Polyethylene wax is relatively hard; the hardness ranges between 2 to 4 on the Mohs scale. Because of this property, wax will become an excellent lubricant that does not wear easily. It will also provide structural integrity for applications that require the wax to hold its shape.
• Low-Temperature Performance: Contrary to some natural waxes, polyethylene wax features very good performance at low temperatures: its main properties do not decrease noticeably under cold conditions, therefore allowing its application for low-temperature functionality.
• Low Viscosity:   Polyethylene wax has a very low viscosity, which means ready flow when heated. This property is very important for applications such as coatings and inks, and also as a processing aid in the manufacture of plastics and rubber.
• Water and Chemical Resistance:   Polyethylene wax has a very high resistance to water and a host of other chemicals. The resistance ensures that the wax remains effective and does not deteriorate when in contact with moisture or harsh chemicals.

Chemical Properties:

• High Melting Point: polyethylene wax boasts a high melting point, typically ranging from 100°C to 140°C (212°F to 284°F). This allows it to withstand high processing temperatures without undergoing significant degradation.
• Thermal Stability: polyethylene wax exhibits excellent thermal stability. This means it can maintain its chemical structure and properties even at elevated temperatures, making it suitable for applications exposed to heat.
• Low Water Solubility: Polyethylene Wax is insoluble in water, making it an effective moisture barrier in coatings and other applications where water resistance is critical.
• Compatibility: In general, polyethylene wax is compatible with all other types of waxes, resins, and polymers. Due to this reason, modifications or customization of formulation to reach a specific property in various applications can be done by simple blending.

Application and uses of PE wax

PE wax, with its unique characteristics of low molecular weight and hardness and excellent lubrication and chemical resistance properties, is an industrially and commercially versatile material. Some of the major uses are as follows:

Plastics and Polymers

• PE Wax is utilized as a lubricant and processing promoter during the manufacture of plastics through different molding techniques, such as extrusion, injection molding, and blow molding. It reduces friction, improves polymer flow, prevents mold sticking, and thus enhances efficiency, surface finish, and production rate. These improvements contribute to higher productivity and lower operational costs.

Coatings and Paints

• PE wax enhances scratch resistance, brilliance, and surface regularity for coatings. The high demand for the use of PE wax in automobile finishes, industrial coatings, and decorative areas can be attributed to its smooth application and quality finish. It is very important in such industries for durability and aesthetic appeal.

Hot Melt Adhesives

• As a primary ingredient in hot melt adhesives, PE Wax provides an optimal balance of melting point control, bonding strength, and tack reduction. Applications range from packaging and bookbinding to woodworking and beyond. These properties ensure reliable and long-lasting adhesive performance.

Rubber Processing

• In the rubber industry, PE Wax works as a lubricant and processing aid by improving mold release properties, reducing friction, minimizing machinery wear, enhancing flexibility, and providing resilience in the products of rubber. This leads to superior and long-lasting quality in the rubber components..

Paper and Printing

• PE Wax improves surface smoothness, gloss, and printability in paper coatings and printing inks, while also enhancing moisture resistance for food packaging and other paper-based applications that need durability. The combination of features ensures vividness and durability in the print.

Cosmetics and Personal Care

• PE wax is a critical raw material for lipstick, deodorant, and lotion products, as it adds texture and stabilizes formulations for smooth applications and enhanced skin feel. In this regard, the attributes will be important during the formulation of high-class cosmetic products.

Food Packaging

• PE Wax is used for water and grease resistance in food packaging films and containers. It forms a protective barrier against impurities while maintaining flexibility for effective sealing and preservation. These benefits ensure the highest safety and shelf life of packaged goods.

Textile and Leather

• In textiles, PE Wax increases smoothness, water resistance, and strength, while in leather products, it provides softness and flexibility and gives a quality finish. With these improvements, the textiles and leather items become more attractive and durable.

packing of pe wax

The PE wax has proper packaging, which ensures its quality during storage and transportation. The packaging is available in powder, flakes, or granule forms, with the packaging meeting the industrial requirements and those of the customer.

Common Packing Options

• 25 kg Bags: Made from durable polypropylene or multi-layered paper, these bags are moisture-resistant and easy to handle.
• 500 kg – 1,000 kg Jumbo Bags: Ideal for bulk orders, these robust woven polypropylene bags include inner liners for added protection and lifting loops for safe handling.
