Injection Molding

Producing caps and toys with tight tolerances and high-quality finishes requires running high-performing resin on converter lines. At Shell Polymers, we understand all too well how important the qualification process is to injection molders. One of our quality measures lies in the injection molding machines we use—which can measure the pressure in different mold parts to provide valuable insights that can help converters better understand our polymers’ performance before running our material on their equipment.

Grade Slate 101

Understanding how we name our grade slates will be key to choosing the right melt index and density you need. Check out our unique naming convention below to know exactly what to look for when perusing our product bulletins.

Density

Process

Melt Index

Comonomer Type (Film)

Additives

Density is reflected by the first two numbers found in the nomenclature sequence, which in this instance is 18. These numbers represent the last two significant digits of the density value. See examples below.

18 = 0.918 density
53 = 0.953 density
63 = 0.963 density

Leveraging high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) in applications makes durable products that can also be abrasion-and chemical-resistant. So when a part needs to be strong, versatile, and produced quickly, HDPE and LLDPE are strong contenders.

HDPE Resin

HDPE is a popular choice across a variety of industries because of its moisture and chemical resistance, impressive tensile strength and durability.

LLDPE Resin

LLDPE has a variety of benefits and is known for its resistance to breaking or staining, molding capabilities and the ability to produce complex shapes.

Injection molding is used in a number of markets ranging from Food & Beverage to Toys, and more.

Food & Beverage

Polymer packaging made with LLDPE or HDPE helps protect food from delivery and shipping to your kitchen.

Automotive

Crates in this market benefit from the sheer tensile strength that only HDPE can provide.

Household

Durable and leak-resistant containers for household chemicals can be made with HDPE or LLDPE.

Industrial

Manufacturing products such as crates, blown film and drums benefit from HDPE or LLDPE, depending on the use case.

Toys

LLDPE and HDPE helps provides toys with flexibility and durability—keeping them safe from little hands that might break them.

Agriculture

HDPE and LLDPE are used to create containers that can safely store agricultural products.

Polymer Packaging

Cosmetics containers made from HDPE are more durable, making the trip down the assembly line to the consumer’s cabinet a smooth one.
