HLLFOAM is more than just a foam manufacturer. We are also an extension of your design and engineering teams. Our success is largely determined by our ability to work with you to design and develop innovative engineered foam solutions for your new application. Our sales and product development team members have extensive experience working closely with customers throughout the design and development process. Ideally, we are involved in the conceptual phase and can educate our customers on materials and their properties, our production capabilities and process limitations, etc. our production capabilities and process limitations, etc. Our involvement at an early stage often helps minimize the time required to develop new foam components.

Another advantage of working with HLLFOAM is our in-house tool shop. We not only design but also build the molds, cutting dies, and fixtures we use to manufacture your parts. In doing so, we are able to build cost-effective, durable tools that will hold tight tolerances for the life of a project. Having our tool shop in our own facility allows us to expedite any necessary modifications during the prototype stage. It also allows us to make any required repairs to production tools with very little downtime.

HLLFOAM has built a very loyal customer base by providing innovative foam solutions and consistently delivering an exceptional level of customer service. From your initial contact with an HLLFOAM salesperson, through the development process with our engineers, to our customer service associates, we strive to be the most responsive, customer-driven foam manufacturer in the industry.

Viscoelastic Slow Recovery Memory Foam

Viscoelastic slow recovery polyurethane memory foam exhibits slow recovery time to return to its initial form. It has a low ball rebound, and is a highly conforming PU material. 

Self-Skinning Polyurethane Sponge

Integral skin foam offers a more high-density and thicker dense outer skin which is ideal for a number of applications including arm rests. 

Polyurethane Molded Toys

Hll Foam molded polyurethane toys are constructed from a range of flexible PU foam and solid elastomer materials. We specialize in molding foam and polymers to fit customer’s exacting needs.

Injection Molded Polyurethane

Leveraging its 16+ year heritage HLLFoam has applied its expertise in polyurethane (PU) to the manufacture of components and finished products goods for industrial and consumer OEM partners.

We produce self-skinning, flexible, viscoelastic polyurethane foam products. Our Industrial team has deep, experience-based knowledge of partner product needs, from materials’ shock-absorbing properties or anti-static/static dissipation, to complex shapes molded around metal or plastic structural inserts.
