SCHÜTZ SMP – prevents your products from vanishing into thin air.

The SMP (Surface Modified Plastics) method developed by SCHÜTZ effectively seals plastic containers to ensure that leakage of contents (permeation) is reliably prevented.

SMP fluorination is perfectly suited for all plastic containers that are used for transporting or storing soluble, aromatic filling goods and aromatic substances. SMP treated packaging is used mainly in the chemical industry, the automobile sector as well as in transport services, for example as:

Gasoline and fuel oil tanks
Containers for transporting sensitive substances
Containers for chemicals

The superior mechanical properties of HDPE, including resistance to extension, expansion, hardness, resistance to cracking susceptibility as well as thermal properties and low-temperature behaviours are not influenced by SMP treatment. In return, the environment benefits from the extremely low rates of permeation.

SCHÜTZ fluorination service

SCHÜTZ has a state-of-the-art, fully equipped, SMP application plant at its disposal to treat transport and storage containers.

We also offer fluorination services exclusively for our customers: in this way, containers made from HDPE,
LDPE or PP provide safe and environment-friendly packaging for all kinds of hazardous substances.
