Isolon Block Sport — polyethylene foam archery backstop
Block target for ranges and training: absorbs impact, resists moisture, works in both frost and heat.
Produced by hot pressing of cross-linked polyethylene foam granulate into a rectangular block. The material is used as thermal and acoustic insulation, impact energy absorber, flotation material and for sports applications (archery backstops / arrow stops). It complies with TU 2244-026-00203476-2002.
−60…+75 °C (up to +100 °C without mechanical load)
1000×1000×90 mm as per TU (commercial size – 100×100×10 cm)
Environmentally friendly, safe material
Does not absorb water and can be used as a buoyant (floating) material.

Characteristics (Sport & Stroy blocks)
| Key parameters | |
|---|---|
| Series / type | Isolon Block — hot-pressed crumb of foamed polyethylene |
| Variants |
Sport: 1000×1000×90 mm (≈100×100×10 cm) Stroy: 1000×1000×50 mm (≈100×100×5 cm) |
| Service temperature | −60…+75 °C; without mechanical load up to +100 °C |
| Moisture resistance | Does not absorb water, can be used as a buoyant material |
| Acoustic performance | Reduces impact noise transmission and vibrations |
| Fire behaviour | Combustible material — store and use away from open flame and intense UV |
| Standard | TU 2244-026-00203476-2002 |
Mechanical properties
| Structure | Closed-cell, pressed PE crumb |
| Cushioning | Effectively absorbs shocks and vibrations, recovers its shape |
| Strength | Withstands mechanical loads (shots, impacts, pads under equipment) |
| Cold resistance | Operates down to −60 °C without structural damage |
According to TU, slight shrinkage along the edge down to ≈950×950 mm is allowed
(a feature of the hot-pressing process).
Notes
- Sport is used as an arrow stop / target block.
- Stroy is used in construction and industry as a cushioning and insulation element.
- Both variants comply with TU 2244-026-00203476-2002.
Storage conditions
Store blocks in covered warehouse areas with natural ventilation.
Protect from moisture, heat and direct sunlight.
Keep at least 1 m away from heaters and other heat sources.
Stacking in one or two layers on pallets is allowed, without excessive deformation.
Shelf life
Warranty shelf life — 12 months from the date of manufacture.
After expiry, blocks may only be used after testing confirms
compliance with TU 2244-026-00203476-2002.
Packaging
Each block is labelled with: material type, version (Sport / Stroy), dimensions,
batch number, date of manufacture.
Custom packaging or palletisation is available upon request.
Transportation
Transport in covered vehicles in accordance with general cargo regulations.
Protect blocks from moisture, dirt and mechanical damage during transport.
The consignee is responsible for preserving the product condition during transportation.
Isolon Block — Sport (10 cm) and Stroy (5 cm)
Archery backstops and construction shock-absorbing / insulating blocks
Sizes, applications and features of Isolon Block
Two standard items in stock: Block Sport 100×100×10 cm (archery backstop) and Block Stroy 100×100×5 cm (construction / industrial use). Slight edge shrinkage to approx. 0.95×0.95 m is possible (typical for hot-pressed foam crumb blocks).
| Item | Size | Application | Notes |
|---|---|---|---|
| Isolon Block Sport | 100×100×10 cm | Archery backstop / target | High energy absorption under impact; blocks may be joined along the edges to assemble larger targets; covers / hanging systems can be added. |
| Isolon Block Stroy | 100×100×5 cm | Cushioning, pads, bumpers | Hot-pressed PE-foam crumb block; used as protection in transport, vibration damping and as thermal / acoustic insulation inserts. |
- Approx. weight: ~10–14 kg for 100×100×10 cm; up to ~7 kg for 100×100×5 cm.
- Thermal conductivity (typical): 0.045–0.055 W/m·K. Service temperature: −40…+100 °C (no mechanical load near upper limit).
- Compression strength (typical): at 10% strain ≥0.03 MPa; 25% ≥0.05 MPa; 50% ≥0.15 MPa.
- Technology: hot pressing of closed-cell PE-foam crumb into plates / blocks (colour shade may vary from batch to batch).
Assembly of a stand, mounting of the block and a paper target on the front side.
When the centre area is worn out, the block can be rotated, the centre replaced
or a second block added to extend service life.
Cutting Stroy blocks (50 mm) to required size and using them as pads between
layers of equipment or goods — reduced breakage and scratches, moisture-resistant support.
Cut bumpers protect edges and surfaces during assembly and moving,
absorbing impact loads and reducing vibration.
