PEEK – FDA approval across food industry
JUNDE PEEK provide the most stringent food contact material requirements
for safety, quality and regulatory compliance of the industry with FDA (Food and Drug
Administration) approval for thermoplastics machining operators in this field.
PEEK can replace metals in a variety of applications due to the light
weight and easy-to-machine properties in plant and machinery for food processing, beverage
bottling machinery. JUNDE PEEK materials enhance production, speed and safety in the
manufacturing process.
Our technical experts can assist you in choosing the most appropriate PEEK
materials for your food contact plastics application, including product design, mapping, cost
budgeting.

Food Industry Case Studies
PEEK guide block, roller and bottle clamp block are applied in
beverage filling equipment. Canning equipment of Master Kong, UNI-PRESIDENT and others for green
tea and black tea is widely using PEEK guide block. Meanwhile, they are used in large quantity
in canning production line in Coco cola.
PEEK5600 – Series Advantages
Low Specific Gravity
Replaces titanium alloy (4.5g/cm³) and aluminum alloy (4.5g/cm³) to achieve lightweight.
High Wear Resistance
The melting point is 343°C, long-term use at 260°C, the thermal deformation temperature of the composite material is about 330°C and higher temperature resistance.
High Strength
The mechanical properties of PEEK modified by chopped fibers are slightly lower than those of aluminum alloys.
Corrosion Resistance
It has corrosion resistance to most organic solvents such as acids and alkalis. It is corroded by halogens and strong acids at high temperatures and is soluble in concentrated sulfuric acid at room temperature.
Thermoplastic Material
Fatigue resistance and impact resistance are significantly better than thermoset materials, have a longer life, are environmentally friendly, and are recyclable.
Material Stability
It better reflects the characteristics of low gas release in outer space and a vacuum coating environment.
Wear Resistance
High hardness and low friction coefficient.
Dimensional Stability
PEEK reduces the expansion coefficient and thereby drastically reduces the swelling risk.

answer.
PEEK Properties
1
Environmental and innocuous. PEEK itself is
environmental and innocuous and has been certificated by FDA. It can be used in contact with
food and has no contact duration limit.
2
Low hygroscopicity and hydrolysis resistant. It
can work in the water and steam for a long time.
3
Wearing resistant. PEEK and its compound materials
are of leading wearing resistance in plastics which is three times better than copper alloy.
4
Corrosion resistant. Food processing and packing
equipment are designed as self cleaning to guarantee the quality of food and safety.
Cleaning solutions are generally composed by acid and chlorine. PEEK has astonishingly
stable chemical structure and has good corrosion resistance facing all kinds of organic and
inorganic solutions, even in the high temperature. It solves the difficulty that metal and
ordinary plastic can’t bear corrosion for a long time.
5
Self-lubricating. It can serve stable work without
oil for a long time. This can avoid using of metal parts which need oil lubricant and bring
contamination to packing machine and food. At the same time, the appearance of packing
machine would be cleaner.
6
Easy to form. PEEK has good processing and forming
characteristics. It can take processing procedures like injection molding, machining,
milling, drilling, tapping, NC, CNC, etc to process all kinds of complicated special-shaped
parts conveniently according to the drawings or samples of customers.
7
High temperature resistant. Packing machine or
food is normally disinfected by high temperature and lasers. The continuous using
temperature of PEEK is as high as 260°C. It can maintain good mechanical strength even in
300°C, which can be heated in hot air furnace, digester, contact heater or microwave oven.
Therefore, PEEK parts can bear repeated disinfection, including 200°C autoclave
disinfection, 143°C flash disinfection, γ-laser disinfection and ethylene oxide disinfection
lamp. It won’t lose mechanical properties and still has good stress cracking resistance.
8
Because of outstanding characteristics and
advantages like wearing resistance, high temperature resistance, high strength,
self-lubricating, etc of PEEK, we can guarantee the continuous using of parts on equipment
for a long time and avoid shutdown of equipment caused by changing parts.
