High-Clarity Commercial Freezer Door Frames & Display Profiles
Thermal efficiency in commercial refrigeration relies on precision components. Our custom-extruded PC and PMMA thermal break profiles and track strips are engineered to act as effective barriers against heat transfer, significantly minimizing cold air leakage and supporting anti-condensation systems in commercial freezers.
Precision Thermal Break Strips
Extruded to tight tolerances, these plastic strips fit perfectly into aluminum or steel frames to interrupt the thermal bridge, drastically reducing heat transfer.
Low-Temperature Toughness
Formulated specifically for cold chain environments, our PC/PMMA profiles maintain their flexible snap-fit properties without cracking or becoming brittle at -40 degrees.
Seamless Co-Extruded Seals
We offer rigid-flexible co-extrusion for track profiles, combining a rigid base for stable glass door sliding with a soft sealing lip to block ambient moisture.
| Extrusion Strip Properties | Polycarbonate Strip | Acrylic Strip | Cold Chain Application |
|---|---|---|---|
| Thermal Conductivity | Low (0.20 W/m·K) | Very Low (0.19 W/m·K) | Acts as an efficient thermal break inside metal frames. |
| Dimensional Stability | Excellent (Low shrinkage) | High (Maintains straightness) | Ensures long extruded strips stay perfectly straight during temperature shifts. |
| Flexibility & Snap-Fit | High impact; ideal for snap-in claws | More rigid; suitable for slide tracks | PC is perfect for strips that need to snap repeatedly into aluminum slots. |
| Surface Wear Resistance | Good standard resistance | Excellent (High scratch resistance) | 高度推荐使用 PMMA 作为滑轨条（Sliding Tracks），耐磨且滑动顺畅。 |

Beyond Standard Capabilities: Heavy-Duty, Thick-Wall Custom PC Profile Engineering
Many extrusion factories decline complex, thick-walled engineering profiles due to the extreme risks of internal bubbling and structural warping. At EXLONG, we turn manufacturing limitations into industry standards. Through our proprietary slow-tempering stabilization technology, we successfully deliver ultra-solid Polycarbonate bars and track profiles with zero internal voids and exceptional linear straightness.

While standard extruders suffer from internal voids, vacuum bubbles, and micro-cracking in thick polymers, our customized slow-cooling calibration process ensures a 100% solid, crystal-clear structure throughout the entire profile cross-section.
Micro-Precision Internal Tracks
Maintaining perfectly parallel internal slots in a high-thickness solid PC bar is a recognized engineering challenge. Our mirror-polished mandrel dies lock complex dimensions (like snap-fit claws and sliding grooves) tightly in place during the critical cooling phase.
Zero Thermal Warping & Die Lines
Thicker extrusions require longer barrel residence times, which often causes material degradation (yellowing or black spots). We optimize melt-filter systems and tool design to achieve an optical-grade finish with zero surface die lines and maximum wear resistance.

Commercial Refrigeration FAQ
Thermal Efficiency, Material Safety, & Lifespan
What materials can be coextruded?
A wide variety of thermoplastics can be coextruded, including (but not limited to) ABS, PVC, polycarbonate, acrylic, polyethylene, polypropylene, and thermoplastic elastomers (TPEs).
What are the advantages of coextrusion?
Enhanced performance: Combining materials for specific properties.
Cost-effectiveness: Using less of a more expensive material by combining it with a cheaper one.
Design flexibility: Creating complex profiles with varying characteristics.
Improved aesthetics: Adding color or texture to specific areas of the profile.
What are some common applications of coextruded profiles?
Common applications include: window and door frames, seals and gaskets, automotive parts, lighting diffusers, consumer goods, and medical devices.
How is the coextrusion process different from regular extrusion?
Regular extrusion uses a single material, while coextrusion uses two or more materials fed into a single die, bonding them together during the extrusion process.
Can coextruded profiles be recycled?
Recycling can be more complex with coextruded profiles, as the different materials need to be separated. However, some coextruded profiles can be recycled depending on the materials used and the recycling infrastructure available.
How do I choose the right materials for a coextruded profile?
Material selection depends on the specific application requirements, including:
Mechanical properties (strength, flexibility)
Thermal properties (temperature resistance)
Chemical resistance
Weatherability
Cost
What are some design considerations for coextruded profiles?
Design considerations include:
Material compatibility
Layer thickness
Profile shape and complexity
Bond strength between layers
How much does coextrusion cost?
The cost depends on the complexity of the profile, the materials used, and the production volume.
