Used to make large products such as playgrounds, industrial containers and more, rotomolders are among the largest users of linear low-density polyethylene.
Rotomolding Creates Durable Products Across Industries
Rotomolding has managed to penetrate a variety of market segments, such as automotive, building and construction, material handling, medical, toys and storage tanks. This is because of its ability to produce structurally strong and aesthetically appealing hollow and semi-hollow parts.
A labor-intensive process that involves accurately cooking resin powder in a biaxially-rotating oven, it can often be challenging for rotational molders to produce enough parts in a day to keep up with demands while still balancing operating costs. But, with rotomolding capabilities, linear low-density polyethylene (LLDPE) can take on a variety of complex shapes. It remains safe after constant exposure to heat and finished products are low maintenance compared to alternative materials.
Key Markets for Rotational Molders
Injection-molded artificial turf is growing in popularity due to its ability to withstand high temperatures and people walking on it frequently.
Rotomolded LLDPE toys have a variety of benefits, such as their resistance to breaking or staining, and an uncanny ability to mimic the appearance of other materials.
Converters need to provide customers with containers for household chemicals that are tough enough to resist leaks and breaks, and prevent unintentional, and potentially dangerous, spills.
