UPM ProFi Piazza 2019

Product catalog summary

Introduction
UPM ProFi Piazza is an innovative composite material produced in Germany, combining plastic and engineered fibers from self-adhesive label manufacturing. It is lignin-free, offering superior color durability compared to traditional wood-plastic composites (WPC) and is resistant to oil spills and stains.

Material and Surface
The material features a high-performance polymer cap surface and is available in two profiles: Piazza S1-25 with natural hardwood embossing and Piazza S2-25 with a dual surface of hardwood embossing and a fine grooved texture.

Physical and Mechanical Properties
Key properties include:

Linear Mass: 3.3 kg/m (S1-25), 4.0 kg/m (S2-25)
Bending Strength: 11 N/mm² (S1-25), 19 N/mm² (S2-25)
Friction (wet/dry): >36
Thermal Expansion Coefficient: 4.0 x 10^-5 1/°C
Water Absorption (24h): <2.5%
Swelling (24h): <1%
Flexural Modulus: 1100 N/mm² (S1-25), 1250 N/mm² (S2-25)

These values are characteristic and not for strength calculations in serviceability.

Profile Dimensions
Both profiles have dimensions of 25 mm x 140 mm, with length options of 4 m and 5 m.

Thermal Expansion
UPM ProFi Piazza expands and contracts with temperature changes. For example, a 4 m board can expand by approximately 6 mm with a 40°C temperature increase.

Scratches and Surface Abrasions
Superficial marks may occur from dragging heavy objects but do not affect structural performance. Sanding the surface is not recommended.

Colour and Weathering
The material is virtually lignin-free, preventing typical greying. Colors may fade slightly over time, especially in high UV areas. Regular cleaning with water and a brush is advised to maintain appearance.

Environmental Impact
UPM ProFi Piazza is made from approximately 75% recycled content, is non-toxic, PVC-free, and recyclable. It reduces landfill and waste incineration by utilizing label surplus material. The product does not require painting or staining, reducing associated pollutants.

Catalog excerpts

UPM ProFi Piazza Technical Specification MATERIAL UPM ProFi Piazza is an environmentally innovative composite material made in Germany that combines the best qualities of plastic and engineered fibers which fall as surplus by-products in self-adhesive label manufacture and processing. UPM ProFi Piazza is lignin free and therefore offers better colour durability than traditional WPC. The material contains no harmful chemicals. Compared to traditional WPC boards, the closed surface is also more resistant to oil spills and stains. PROFILE SURFACE Solid profile made by extrusion technology High performance polymer cap surface. Piazza S1-25: Natural looking hardwood embossing with bottom scallops. Piazza S2-25: Natural looking hardwood embossing on one side and a brushed, fine grooved surface on the other. Test method Linear Mass Bending Strength, N/mm² Thermal Expansion Coefficient, 1/°C Flexural modulus, N/mm² *Based on CEN/TS 15534 wood plastic composites (WPC). The values above are characteristic values from quality tests and therefore not for strength calculations in the serviceability state. PROFILE DIMENSIONS 25 mm x 140 mm; length 4 m & 5 m UPM ProFi Piazza will expand and contract with changes in temperature. Piazza S1-25 140 +1.0/-2.0 mm
