Neoprene replaced by L.D.S Rubber

For many years we have used neoprene as the elastomer in most Mason Ind products. The main advantage of Neoprene was longevity and consistancy when compared to rubber. Rubber however is a better isolator exhibiting a lower natural frequency for the same deflection.

With the advent of new technology Mason Industries & Mercer Rubber Co have been able to combine the advantages of neoprene with the superiority of rubber with a new formulation called L.D.S (Low Dynamic Stiffness).

Neoprene Products Now L.D.S

The neoprene elements in Mason acoustic ceiling hangers, wall isolation products, as well as Mason floating floor products have now been replaced with the new L.D.S (Low Dynamic Stiffness) rubber.
Mason Industries rubber mounts and pads are still available in neoprene although there are LDS rubber versions available.

Mason literature is currently being updated to show L.D.S (Low Dynamic Stiffness) in place of the neoprene where applicable.

Longevity of Natural Rubber

A study commission by the Malaysian Rubber Board on the The Longevity of Natural Rubber in Engineering Applicationsfound that all the evidence points to a service life well in excess of 100 years for well-designed and well manufactured natural rubber load bearing components. Good design and manufacture are assured by the wealth of information and advice available: natural rubber is backed by 50 Engineering Data Sheets giving detailed physical and dynamic mechanical properties for a comprehensive range of vulcanizates. The publication of the EDS serie has led to claims that natural rubber is the best characterized engineering elastomer available: the evidence here shows without doubt that it is also the longest-serving.

Mason Industries have applied the above information in the production of our Low Dynamic Stiffness – L.D.S rubber. All our products are produced to the highest standard and as such we are industry leaders. We so out-rank our competitors that Mason Industries products are often specifically specified for a job.

Super W Pad

Super W pads feature unique waffle pockets which allow for greater deformation of the material, providing excellent isolation performance. Super W anti-vibration pads can be supplied in multiple configurations to suit most situations.

Rubber Mounts & Pads

Anti-vibration mounts & pads supplied by Mason U.K. are manufactured from high quality bridge-bearing neoprene or L.D.S rubber. Both materials are certified to meet or exceed applicable standards.

Elastomeric Isolation Bearings

Elastomeric bearings can be made from a variety of materials and are very effective against most medium to high frequency vibration sources. The material choice depends on the environment, but natural rubber is the most common choice due to its low dynamic stiffness.

HG Grommets Bolt Isolation Bushings

HG Grommets are rubber bolt isolation washer bushings designed to allow a fixing to be passed through without compromising the benefits of an anti-vibration layer.

W Pad

Waffle pad is a thin anti-vibration mat featuring a series of square cut outs which increase the amount of material which can deform under load.

ND – Double Deflection Rubber Mounts

ND Double Deflection Rubber Mounts are used to isolate mechanical plant and machinery as well as wooden floating floors.

Jack-Up LDS Rubber Floating Floors

The Mason FSN Jack-Up acoustic floor system can be used as the crucial part of achieving box in box construction for studios or rooms requiring a high level of acoustic separation or simply providing acoustic or impact isolation from one area to another.

Form Work Floating Floor

The formwork system is the traditional method of creating a floating floor. Isolators are placed at regular intervals across the area and the floating floor built on top.

L.D.S Rubber Hangers

Acoustic, LDS (Low Dynamic Stiffness) rubber (previously neoprene) hangers can be used for suspending ceilings or mechanical plant.
