Compounds gain listing

Trelleborg Sealing Solutions has two compounds that are listed by NSF International as conforming to the requirements of NSF/ANSI Standard 51 — Food Equipment Materials.

Turcon MF5 compound has achieved this status, joining Turcon MF6.

They are part of the MF range of materials specifically engineered for demanding processing environments, including food and beverage production.

Based on ultra-clean technology, compounds are manufactured from high-purity PTFE grades and additives.

Their smooth finish, with high gloss and low porosity, avoids the risk of contamination build-up and reduces particle shedding. Each batch of MF material is manufactured using high-purity material only and can be issued with a certificate of conformity.

The MF materials offer: operating temperatures from -200 to +260 °C; almost universal chemical compatibility; low long-term compression set characteristics; good friction and sliding properties; especially suitable for rotary applications; high wear resistance; minimal creep and permeation; a surface finish that minimises contamination risk; performance in a broad range of chemical media including organic and inorganic oxides, acids, alkalis, amines, esters and steam; compliance to FDA 21 CFR177.1550; NSF/ANSI standard 51.

The materials are available in custom profiles along with Variseal and, specifically for hygienic and super clean environments, Variseal Ultra-Clean.

In this seal, the energising spring is fully enclosed, eliminating dead space and the consequential risk of contamination.
