Application
General properties
®
Mesamoll is characterised by
1. A good compatibility with a large number of polymers.
2. An excellent gelling capacity with a large number of polymers including PVC, resulting in lower processing
temperatures and shorter processing times.
3. A good resistance to weathering.
4. A high saponification resistance due to its chemical structure. This is especially beneficial for articles
which come into contact with water and alkalis.
5. Favourable dielectric properties for high frequency welding, leading to short cycle times.
Applications
®
Mesamoll is used as a plasticiser for a wide range of articles based on polyvinyl chloride (PVC), polyurethane
(PUR), and rubber (NBR, NR, SBR, SBR/BR, IIR, CR). It allows the production of AgBB conform articles. Typical
applications are:
1. PUR-based sealing and adhesive systems (1-component and 2- component systems) mouldable, easy-to-
process sealants for filling or covering joints in structures and parts of buildings.
2. Cleaning: Rinsing and service fluids for polyurethane foaming machinery.
3. Rotational Moulding: Vinyl articles made by rotational casting.
4. Dip Moulding: PVC one way gloves and other articles which are produced by dip moulding.
5. Calendering: Films for different applications such as automotive industry, for tunnel linings and other
construction applications, for electrical insulation and adhesive tapes. Because of its good saponification
®
resistance, Mesamoll can be used in the production of swimming pool covers, shower curtains.
6. Extrusion: Profiles for the automotive industry, jointing strip, tubing, weathering and alkali-resistant
structural profiles, blown film.
7. Injection Moulding: Work boots, technical articles.
8. Coatings (including spreading): Coatings for air-supported structures and tents, occupational and
protective clothing, rain-wear, bath mats, expanded film, floorcoverings, wall paper, imitation leather.
Packaging
Road tankers, 1000 kg PE-containers, 240 kg metal drums.

Storage conditions
®
Mesamoll should be kept in its tightly sealed original container in a dry place. If stored properly, the product is
stable for 2 years.
®
During storage, Mesamoll should not come into contact with iron for prolonged periods since this may cause
discoloration of the plasticizer, especially at temperatures above 40 °C. The materials recommended for transport
and storage containers are: aluminium, stainless steel (1.4541 resp. 1.4571), iron containers with an oil-resistant
coating such as DD coating, tanks in uncoated polyester or, preferably, with an impervious DD coating. As
® ®
sealants materials should be used which are resistant to Mesamoll as Teflon (DuPont
®
Polytetrafluoroethylene) or Centellen (Synthetic fibre based, Fa. Hecker Werke GmbH & Co KG). To ensure that
®
MESAMOLL can be easily pumped from outdoor tanks even at low temperatures, tanks should be well
insulated and/or the plasticiser heated slightly if necessary. Warm water has proved to be a suitable heating
medium. Heating coils should be made of aluminium or, if necessary, of stainless steel 1.4571.
Handling
A receiving inspection is recommended. The product should be stored in its tightly sealed original container in a
cool, dry place. Once opened, containers should be resealed tightly after removal of product. Consult material
®
safety data sheet (MSDS) for additional handling information on Mesamoll .
