LDPE 1922T is a Low-Density Polyethylene grade specifically developed for injection moulding applications. This material is produced via the tubular process, making it a special grade within its category. Its primary function is to offer an excellent balance between flow properties, crucial for efficient processing, and robust mechanical properties, which are vital for the durability and performance of the final moulded items. The significance of LDPE 1922T lies in its ability to facilitate high-quality manufacturing of goods that require both precision in moulding and strength in use.
1922T possesses several distinguishing features:
The 1922T grade excels in various applications requiring a careful equilibrium between material flow during the moulding process and the mechanical resilience of the finished product. Typical use cases include:
It is specifically designed to meet the demands of industries that need easily processable materials that also deliver resilient and durable consumer goods.
The balanced flow and mechanical properties of LDPE 1922T deliver significant real-world advantages:
The primary target audience for LDPE 1922T includes manufacturers and processors within the plastics industry who utilise injection moulding techniques. Specifically, industries involved in the production of consumer goods, such as toy manufacturers, household goods producers, and companies specialising in packaging components like snap-on lids, would benefit most from this material’s unique properties.
LDPE 1922T is supplied in the form of pellets. Customers have the option to receive the material either in bulk or in 25 kg bags. For larger deliveries, the bags are provided on shrink-wrapped pallets, with each pallet having a total weight of 1375 kg. This packaging ensures the material’s protection during transport and facilitates efficient handling and storage for industrial users. The producer of this material is LALEH Petrochemical Co..
