求翻译：While many of your competitors have compromised the quality of their inflatables by turning to cheaper materials and overseas manufacturers, we have stayed our course in continuing to use only the best materials, and by continuing to manufacture our units here in our factory. The quality of the predominate material, vinyl, is the key element in determining the lifespan of the inflatable unit. The vinyl used on our inflatables has the highest tear strength and can withstand drastic changes in temperature without losing its vibrant color. Vinyl is interwoven to maximize strength and durability making for a better end product. Our vinyl is also lead free providing for a sage and non-toxic playing environment. All material used in manufacturing our inflatables are Fire Retardant, Water proof and meet the SGS tests.是什么意思？
