Rainbow slides retain vibrant, long-lasting color thanks to premium core materials and advanced coloration technology. The slide body is manufactured from brand-new high-density polyethylene (HDPE), a top-tier weather-resistant raw material. UV stabilizers are incorporated during production to form an anti-UV protective layer, delivering outstanding anti-aging performance. This effectively blocks intense ultraviolet radiation and prevents oxidation and color fading caused by prolonged sunlight exposure.

  For coloring, we adopt high-grade masterbatch such as Bayer masterbatch imported from Germany. These masterbatches boast exceptional compatibility with the HDPE substrate. All finished slides pass rigorous xenon lamp aging tests, with color difference strictly controlled within minimal tolerances. As a result, the slides maintain bright, uniform hues and resist discoloration even after years of heavy outdoor operation.
