HOSES

INTRODUCTION

POLYAMIDE 12

POLYAMIDE 11

We offer hoses in a wide variety of materials and dimensions.

PA 12 is a very suitable material for rigid and semi-rigid hoses.

The objective is to find a product which meets the customer's requirements concerning functionality, properties and price.

The excellent mechanical properties offers very good resistance to pressure combined with good chemical resistance to oils, grease and different types of fuels.

Bio-polyamide 11 is based on a renewable vegetable source that originates from castor oil and as PA 12 is a very suitable material for rigid and semi-rigid hoses.

Before finally choosing the material it is vital to have a thorough knowledge of the surroundings and conditions in which the hose will be functioning. Wrong choice can cause difficulties during installation, lack of functionality and in worst case collapse of the hose. It is important to know about the following conditions: • Temperatures (minimum and maximum) • Service pressure • Chemical environment • Work environment (impact blows, wear, flexibility, sunlight, etc) Other requirements like colour, food approvals, burnability etc. might also influence the choice.

It is an ideal candidate for pneumatic hoses and break hoses for the automotive industry. Several PA 12 grades fulfils the DIN -norm 74324 and 73378. Our product range covers: • PA 12 PHL (DIN 73378/74324) • PA 12 PHLY (DIN 73378/74324) • PA 12 HIPHL (DIN 73378/74324) • PA 12 H (DIN 73378/74324) • PA 12 AN (Antistatic) • PA 12 SF (Superflex) • PA 12 FR (Railway EN45545)

The excellent mechanical properties offers very good resistance to pressure combined with good chemical resistance to oils, grease and different types of fuels. It is an ideal candidate for pneumatic hoses and break hoses for the automotive industry. PA 11 has excellent resistance to low temperatures, and has a better performance on this particular point compared to PA 12. Several PA 12 grades fulfils the DINnorm 74324 and 73378. Our product range covers: • PA 11 PHL (DIN 73378/74324) • PA 11 H (DIN 73378/74324) • PA 11 SF (Superflex) • PA 11 OF (Off-shore API 17J) • PA 11 FDA (Food)


POLYURETHANE

POLYVINYLIDENEFLUORIDE

POLYOLEFINS

PUR is suitable material for flexible hoses.

PVDF is characterized by excellent mechanical properties, which is the best of all fluoropolymers. Chemical resistance is better than that of PA 11 and PA 12, but not at the same level as PFA or PTFE. This is also the case for the thermal resistance.

Polyolefins are characterized by mechanical and thermal properties in the low end, but at the same time quite good chemical resistance.

PUR has excellent flexibility and bendability and is very resistant to "kink". Resistance to pressure and chemicals are considerable lower than that of PA 11 and PA 12. PUR is mainly used, when minimal bending radius is a requirement. PUR has a glossy surface and several grades are transparent. The product range include a grade approved for food contact according to the American Food and Drug Administration (FDA) and drinking water according to DVGW W270. Our product range covers: • PUR S98 (Ester 98A) • PUR S88 (Ester 88A) • PUR T85 (Ether 85A) • PUR T85 WATER (Ether 85A) • PUR T88 (Ether 88A) • PUR T95 (Ether 95A) • PUR T98 FOOD (Ether 98A) • PUR T D54FR (Flame retardant)

PVDF is suitable for medical and food contact application due to the high cleanness of the polymer. PVDF is classified as V0 according to UL94 and is approved for food contact applications (FDA / EU) and drinking water application (NSF). PVDF is mainly use for applications demanding a combination of high chemical resistance, mechanical strength and thermal resistance. In many cases PVDF can be used instead of PTFE or PFA, as the mechanical properties are often enough and price and weight is lower. Our product range covers: • PVDF HA • PVDF FX

Recommended service temperature depends on grade, but is in the range of -50°C to +60°C (depending on grade). Polyolefins is mainly used for applications with limited requirements for low pressure and temperature. Several grades are approved for food contact according to the American Food and Drug Administration (FDA) and some European norms. Our product range covers: • LDPE • HDPE • HDPE AN (Antistatic) • HMW-PE • EVA • PP-C • PP-H


PROFILES

INTRODUCTION

PA ALLOY

POLYOLEFINS

Today the applications for profiles in thermoplastic materials are almost endless.

PA ALLOYS aka TCP is an alloy of PA 6 and HDPE, and by means of a special additive two incompatible materials are united This provides a completely homogenous structure complying the best properties from each material.

Polyolefines are comparatively low cost materials, combining a number of good mechanical and chemical properties in a temperature range from -50°C to +70°C (dependent on type).

The property range in the thermoplastic materials means that most requirements can be met and often with considerable advantages as for weight and environment, compared to alternative materials such as metal, aluminium and wood. We have carefully picked materials especially well suited for a number of applications in conveyor, medical and food industries as well as for shop fittings. In addition to the group of polyolefines (LDPE, HDPE and PP) the materials also include polymers such as fluor polymers, polyamides and thermoplastic elastomers. We produce profiles in a dimensional range from approx. 1 mm up to 80 mm.

The advantages are numerous and offers a perfect match for wear profiles in the conveyor industry. • melting point at 220°C • continuous work temperature at +100°C • high rate of rigidity and surface hardness • high durability • low friction(< UHMW-PE) • low thermical expansion • good dimensional stability • outstanding chemical resistance • approved for contact to foods according to European regulations • resistant to hydrolysis • low water absorption

Most of the types have been approved for foods by the American Food and Drug Administration (FDA) and according to a number of European regulations. Our product range covers: • HDPE • HDPE (250) • HMW-PE (500) • HDPE AN (Antistatic)
