3110 Open Cell Natural Rubber
3110 is a soft, conformable open cell natural rubber foam with an average density of 22 lb/ft³ and a compression deflection of 2–5 psi at 25%, the lowest firmness in the open cell natural rubber range. It is rated for service from -20°F to 160°F and exhibits a compression set of 15% at 50% deflection at 158°F. The material is black, available in thicknesses from 1/16″ to 1/4″, and is characterized by anti-slip, high-friction surface properties and exceptional abrasion resistance.

Common industries: Consumer Products, Furniture, Industrial Manufacturing, Material Handling.
3110 is the softest grade in the open cell natural rubber foam range, with an average density of 22 lb/ft³ and a compression deflection of 2–5 psi at 25% per ASTM D1056. Its soft, conformable construction makes it suited for cushion devices requiring impact protection with minimal resistance — applications such as door stops, drawer bumpers, and similar consumer and industrial impact protection uses where a softer foam is preferred over firmer grades.
The material exhibits anti-slip properties and a high coefficient of friction, along with excellent resistance to abrasion and tearing. It can be laminated with a broad range of materials including textiles and cork. Compression set is 15% at 50% deflection at 158°F per ASTM D1056, and compression deflection change after oven aging at 168 hours at 158°F is ±20%. Temperature range is -20°F to 160°F.
What differentiates 3110 from the firmer grades in the open cell natural rubber range?
3110 is the softest grade in the range with a compression deflection of 2–5 psi at 25% and an average density of 22 lb/ft³ — the lowest density in the series. It is designed for applications where maximum compliance and softness are required, such as door stops and drawer bumpers, where firmer grades (3120, 3130, 3140, 3150) would provide excessive resistance.
Why is compression deflection critical for open cell natural rubber foam selection?
Compression deflection at 25% determines how much force is required to compress the foam to a given deflection — essentially the firmness of the cushion. Selecting the correct CFD ensures the foam deflects appropriately under expected load conditions: too soft and the foam bottoms out without adequate protection; too firm and it fails to absorb impact or conform to the mating surface. 3110's CFD of 2–5 psi positions it as the softest option in the range.
What is the service temperature range for 3110?
3110 is rated from -20°F to 160°F.
Is 3110 suitable for regulated environments?
No compliance standards are specified on the manufacturer's TDS for this material.
How should 3110 be specified?
Specify grade (3110 Open Cell Natural Rubber / H-O part number 3110NRUB), thickness (1/16", 1/8", 3/16", or 1/4"), lamination requirements if applicable, dimensional tolerances, and finished format.
