Colourable resin helps cook up a storm

A Sabic Innovative Plastics product story

The wildly popular Jamie Oliver Flavour Shaker takes advantage of Xylex resin's heat resistance, transparency, durability, resistance to staining and custom colourability.

As any chef will tell you, success in the kitchen depends on choosing the best ingredients.

So when UK chef Jamie Oliver began work with William Levene on the development of a brand new tool for mixing and crushing ingredients, the housewares supplier found the right material - Xylex resin from GE Plastics.

The wildly popular Jamie Oliver Flavour Shaker, which allows cooks to quickly crush, mix, and extract flavor from whole spices for rubs and marinades, takes advantage of the GE resin's heat resistance, transparency, durability, resistance to staining and custom colourability.

Although the Flavour Shaker has won several awards, including Progressive Housewares magazine's Excellence in Housewares Award 2005 for "Top tool or gadget", its unique design created specific material challenges.

The hard ceramic ball inside the shaker must repeatedly hit the sides to crush the spices, so high performance was a requirement.

A clear material would allow cooks to see the blending process.

And William Levene wanted a wide array of colour choices for different product versions and special promotions.

According to Andrew Thornton, head of Design and Product Development at William Levene: "GE's Xylex resin had all the properties we needed to create a product with the quality our customers have come to expect".

"GE helped us deliver a winning design".

In addition to transparency and high resistance to chemicals, heat, and staining, GE's Xylex resin, a polycarbonate (PC)/polyester alloy, is compliant with US FDA and EUFC regulations for food applications.

Its unique properties are provided by the combination of the PC which gives heat and impact resistance, and the alphatic polyester which brings the chemical resistance.

The material withstands the heat and chemicals used in dishwashers, and resists breakdown and cracking caused by reactions to common foods such as vinegar.

For William Levene, a critical advantage of Xylex resin is its colourability.

Using GE's advanced colour-matching services provided by its Customer Innovation centre in Bergen op Zoom, the Netherlands, William Levene was able to quickly manufacture the Flavour Shaker in different colours for future product development.

"When they brought in the colours they needed, we matched them on the spot", said Gabrie Hoogland, Xylex Global Programme Manager for GE Plastics.

GE provided other value-added services to William Levene, including global application development support and rapid delivery of the resin to speed up commercialisation.

GE conducted several lab and field tests, including mould-flow analysis and chemical- and dishwasher-resistance testing.

In addition, the company helped William Levene commission the tools needed to make the application and identify local moulders to accelerate penetration into the European marketplace.

Using a local moulder eliminated long lead times for shipping and helped bring the Flavour Shaker to market more quickly.

"GE's team worked with us from start to finish; from materials choice, to testing and application design support, they've viewed our success as their own", added Thornton.
