INTRODUCTION
Rubber Membranes is a business unit within Trelleborg Building Systems, one of four business areas of Trelleborg.
Trelleborg is a global industrial and distribution group and one of the major producers of industrial rubber products in
The world.
MANUFACTURING
Our manufacturing plant is situated in Varnamo, Sweden. As an operation within one of the global leaders in industrial
Rubber products, we have access to the most cost-effective raw materials and leading process technology. The production
Comprise the complete value-chain from purchasing of raw materials, formulation of compounds, compounding, and two
Layer calendaring, vulcanization in autoclave to finished products in standard rolls as well as panels prefabricated to
Measure. Our activities are ISO 9001 certified, and conducted according to ISO 14001.
RUBBER MEMBRANES
Rubber is elastic not plastic. Vulcanisation creates a stable cross linked polymer structure resulting in unsurpassed
Dimensional stability, elasticity and long term durability in spite of exposure to mechanical stress, atmosphere,
Chemicals, heat, cold, ice and water, ultraviolet radiation or ozone.
Our rubber membranes are chemically stable and contain no environmentally problematic additives such as plasticisers,
Flame- retardants, heat- or UV-stabilisers. They do not release any substances that cause allergies or hazards to the
Environment. Recycling options are available for membranes reclaimed from demolition of old constructions.
Butyl rubber
Butyl membranes have been used for water containment and water proofing construction since the 1940´s. The butyl
membranes have impor tant benefits in their low air and vapour permeability as well as high resistance to ageing, heat,
chemicals and UV-radiation. The features of butyl rubber are utilised in a wide range of water containment applications
ranging from drinking and irrigation water, fish farming and garden ponds. to waste deposits, waste water reservoirs and
agricultural manure pits. In construction, the main applications are sealing strips for facades and ballasted roofing.
EPDM rubber
We introduced EPDM rubber roofing in 1980. Features like fast, clean and easy installation combined with reliable
function and excellent weather resistance have rated EPDM membranes the supreme commercial & industrial rubber
membranes. EPDM membranes can be used for: flat roofs, deck constructions, ponds, landfills and reservoirs.
SPLICING
All the Splicing of Trelleborg rubber membrane systems are based on Hot bond or the new, patented splicing technique
Thermobond. Hotbond is used during prefabrication but can also be used at the installation. Thermobond splicing of
EPDM membrane and accessories is carried out by heat, either from a hot air machine or hot wedge. The splice enjoys
optimum strength and is just as elastic as the rubber membrane itself. The superior service life and properties of
vulcanised EPDM combined with the splicing technique of thermoplastic materials – the best of both worlds.
CHEMICAL RESISTANCE
The chemical resistance depends on concentration,
temperature and time of exposure. The characteristics
of Butyl and EPDM t+20 °C are shown in the
adjacent table.

PACKAGING & STORING
Membranes are rolled on a cardboard core and sealed
with polyethylene film. Each roll is marked with
product name, article- and roll number, dimensions,
date of manufacture and signature.
Rubber membrane rolls must be stored dry, protected
from rain, moisture and dirt. We recommend storage
on pallets covered by a tarpaulin. www.trelleborg.com/rubber_membranes
