Atlas® SEPAP 12/24 Now Available Worldwide


A specialized testing instrument for photochemical aging

Linsengericht - Atlas, a global leader in weathering technology and equipment, is pleased to announce that the SEPAP 12/24, a medium pressure mercury arc testing instrument, is now available worldwide.

This affordable, accelerated photoaging device examines photodegradation mechanisms of polymeric formulations in laboratory conditions. Primarily sold in France previously, Atlas is now launching the device globally due to increased demand in other markets.

Designed as an analytical tool to understand the degradation mechanisms of naturally aging polymers at the molecular level, the SEPAP 12/24 unit replicates the chemical changes in accelerated, controlled lab conditions that are achieved through long-term, natural weathering conditions, from which similar changes in macroscopic properties (mechanical, aesthetical, etc.) can be expected. Use of the SEPAP 12/24 unit is largely accepted by standards committees and by industrial companies in fields where long-term quality control is highly stringent such as:

Automotive

Sport equipment

Plasticulture equipment

Electrical

Building

Industrial Packaging

SEPAP 12/24's design relies on fundamental concepts of macromolecular photochemistry. The units are built as parallelepiped chambers with four medium pressure mercury arc lamps in borosilicate envelops that emit discrete radiation at 290, 313, 365, 405, 436, 547, and 579 nm. The light source is not used to simulate daylight, but to induce the same photochemical processes as daylight. Samples are homogeneously exposed on a rotating support in the center of the chamber. The surface temperature of the samples is accurately controlled and maintained between 50 and 80°C ±1°C through a thermocouple placed behind a reference film with same color and chemical composition as the exposed samples.
