CRITICAL ISSUES REGARDING SILICONE SHEETING

Global demand for silicone sheeting and products is increasing in both the established and emerging markets. But some new suppliers to
the industry are providing sheeting that is far below the exacting quality standards that we take for granted. Some production practices
and end products in some countries are dangerous – to the workforce and the end user. Not all silicone sheeting is suitable for gaskets and
other components used in the food and beverage industry and other critical environments.
In particular there are issues around Extractable Levels, Volatile Loss and FDA White List (Positive List)

Useful Definitions:-
Extractable Levels - are the amount of chemicals that can escape into a liquid from the silicone when it is in prolonged contact with that liquid. Volatile Loss - is the amount of chemicals that escape from the silicone when it is subjected to raised temperatures. FDA White List - list of permitted ingredients & the manufacturer has a legal obligation to use these white list ingredients.

INDEPENDENT TESTING RESULTS
J-Flex Silicone Sheet Products are independently tested and comply with the requirements issued by the US Federal Food & Drug
Administration (FDA) Title 21, Chapter 1, sub-chapter 8, Section 177.2600. They also comply with the German Food Standards BfR
Empfehlung XV and colour bleed test according to BfR Empfehlung part B11 + peroxide levels.

FDA Extraction Test FDA Limit Test Results
1st Extraction distilled water 20.0mg/inch² 0.24mg/inch²
2nd Extraction distilled water 1.0mg/inch² 0.05mg/inch²
1st Extraction hexane 175.0mg/inch² 47.84mg/inch²
2nd Extraction hexane 4.0mg/inch² 1.91mg/inch²
CONCLUSION:
The silicone material tested meets the extractive requirements
specified in FDA 21 CFR 177.2600 Class 1 - Rubber Article
intended for repeated use in aqueous and fatty food contact
(White List ingredients).
BfR Colour Bleed Test
Following tests in which Silicone samples were immersed in water, 10% aqueous ethanol; 3% aqueous acetic acid and Arachis oil.
Test method MSG-LAB-SOP-PML-1006. The test summary reports that the Silicone materials pass the colour bleed test requirements of:
• No Detectable Bleed based on the specifications of the German Budesgesundheitsant (BfR) Empfehlung IX of Part 11.
• The Netherlands ‘Verpakkingen-en-gerbruibsartenbesluit’ of the Netherlands Werewet PartB, Section 7.
• The Belgium Moniteur Belg of 24th September 1976 Section 3 – Migration d’un colorant au pigment
All Silicone elastomer products produced by J-Flex Rubber Products

requirements of the following directives:
GADSL V1.0 (formally known as ILRS List 101 and VDA list 232-101)
EC Directive 76/769/EC
EC Directive 2002/95/EC (RoHS)
EC Directive 2002/96/EC (WEEE)
EC Directive 2000/53/EC (ELV)
EC Directive 2003/11/EC
EC Directive 2004/1/EC
EC Directive 2006/122/EC
And any subsequent
modifications to these
core directives.
None of the following substances are contained in; or used in
the production process of any of the silicone elastomer products
(either solid or cellular) supplied by J-Flex Rubber Products.
Lead (Pb),cadmium (Cd), hexavalent chromium (Cr6+), mercury
(Hg), phthalate based plasticisers, polycyclic aromatic
hydrocarbons (PAH), Short chain chlorinated parafins (SCCP),
polybrominatedbiphenyl ether and polybrominated diphenyl
ether flame retardants (this includes octabromobiphenyl ether,

products and associated production processes are free of any
animal derivitives and are latex free.
None of the cellular silicone elastomer products supplied by
J-Flex contain azodicarbonamide blowing agents.
None of the products supplied by J-Flex contain Perfluorooctane
Sulfonates (PFOS).

BANNED SUBSTANCE USE IN SILICONE ELASTOMER PRODUCTS SUPPLIED BY J-FLEX
Under the Treaty of Rome the test covers all European Member States
The Silicone materials were also subjected to a test to determine levels of hydroxyl-peroxides as laid down in BfR XV Silicone 111 6.
The test summary showed that the silicone materials pass the limit with ‘No positive reaction for peroxide.’
Independent test were carried out by Intertek MSG – Molecular Spectrosopy – The Wilton Centre, Redcar, TS10 4RF. Test report No.
